Synthetic polymers are man-made polymers that are frequently derived from petroleum oil. They can be divided into three categories based on their utility: thermoplastics, elastomers, and synthetic fibres. They are commonly found in a wide range of products all over the world. A wide range of synthetic polymers is available, with variations in both the main chain and the side chains. The backbones of common synthetic polymers such as polythene, polystyrene, and polyacrylates are composed of carbon-carbon bonds, whereas the backbones of hetero chain polymers such as polyamides, polyesters, polyurethanes, polysulfides, and polycarbonates contain other elements (e.g., oxygen, sulphur, nitrogen).
Silicon also forms similar materials, such as silicones, without the need for carbon atoms via siloxane linkages; these compounds are thus referred to as inorganic polymers. Coordination polymers can have a variety of metals in their backbone, with non-covalent bonding. Some common synthetic polymers found in everyday life include Nylons in textiles and fabrics, Teflon in nonstick pans, Bakelite in electrical switches, and polyvinyl chloride (PVC) in pipes.
PET bottles are made of a synthetic polymer called polyethene terephthalate. Plastic kits and covers are mostly made of synthetic polymers such as polythene, while tyres are made of Buna rubbers. However, due to the environmental issues caused by these synthetic polymers, which are mostly non-biodegradable and are frequently derived from petroleum, alternatives such as bioplastics are being considered. They are, however, more expensive than synthetic polymers. Industry produces these to meet people’s needs. Polyethene (the bulk plastic used in packaging) and Nylon Threads are two of the most common polymers we encounter on a daily basis (commonly used in our clothing, fishing nets, etc.)
Overview
Human-created polymers are known as synthetic polymers. Polymers are made up of repeated structural units known as monomers. Polyethene is one of the most basic polymers, with ethene or ethylene as the monomer unit, and the linear polymer is known as high-density polyethylene-HDPE. Many polymeric materials have chain-like structures similar to polyethene. Synthetic polymers, the most well-known of which are nylon and polyethene, are sometimes referred to as “plastics.”
Polymers that are formed by linking monomer units without changing the material are known as addition polymers, also known as chain-growth polymers. All of these are referred to as synthetic polymers. Nylons, which are used in fabrics and textiles, Teflon, which is used in nonstick pans, and polyvinyl chloride, which is used in pipes are examples of synthetic polymers that we use in our daily lives. PET bottles are commonly made of a synthetic polymer known as polyethene terephthalate. The covers and plastic kits are made of synthetic polymers such as polythene, and the vehicle tyres are made of Buna rubbers. However, the use of these synthetic polymers, such as bioplastics and those derived from petroleum, raises environmental concerns because they are said to be non-biodegradable.
These polymers can be synthesised or created artificially in the lab by humans. They are mass-produced commercially in order to meet man’s needs. Plastic bags are one of the most common synthetic polymers that we use almost every day. Synthetic polymers include the majority of today’s plastic materials that people come into contact with on a daily basis, such as plastics used in cars, mobile phones, electrical appliances, packaging material, and so on. Polyethene (PE), polypropylene (PP), polyethene terephthalate (PET), and others are examples. Naturally occurring polymers include cellulose, proteins, DNA, latex rubber, and others. Polythene is the most basic synthetic polymer.
Synthetic polymers examples
So far, various synthetic polymers have been developed. Let us look at a few synthetic polymers that are commonly used in everyday life.
Nylon – Nylon is a synthetic polymer that is also known as polyamide. It was created on February 28, 1935, at the DuPont research facility by a man named Wallace Carothers. Nylon is a popular polymer. Its amide backbone causes it to be more hydrophilic than other polymers. Nylon, unlike the pure hydrocarbon polymers used to make the majority of plastics, forms hydrogen bonds with water.
Polyvinyl Chloride (PVC) – Following polypropylene and polyethene, PVC is the third most commonly produced plastic. This PVC is used in construction because it is stronger and less expensive than alternatives such as copper or iron. PVC is also used to replace rubber in clothing, electrical cable insulation, and a variety of other applications.
Polypropylene – Polypropylene, also known as polypropene, is a thermoplastic synthetic polymer that is used in a wide range of applications including packaging, labelling, stationery, textiles, plastics, reusable containers, laboratory equipment, and so on. Other materials include Thermoplastic Polyurethane, Teflon, Polystyrene, High-Density Polyethylene, Neoprene, and others.
Polychloroprene is an example of a major synthetic polymer.
- Styrene-Butadiene
- Nitrile
- Neoprene
- Silicone
- Polyisoprene
- Styrene-Isoprene
- Copolymers of Epichlorohydrin
Semisynthetic polymer
Chemical modifications are used to create these polymers, which are mostly derived from naturally occurring polymers. For example, cellulose is a naturally occurring polymer; cellulose diacetate polymers are formed by acetylation with acetic anhydride in the presence of sulphuric acid. It is used in the production of thread as well as materials such as films, glasses, and so on. Vulcanized rubber is another example of a semisynthetic polymer used in the production of tyres and other rubber products. Another example is gun cotton, which is cellulose nitrate used in the production of explosives.
Semi-synthetic polymers include rayon and other cellulose derivatives such as cellulose nitrate, cellulose acetate, and others. Thermoplastic polymers are what these are. Cellophane is a thin transparent film made from viscose rayon. Glycerol is used to soften cellophane. It absorbs water, unlike plastic sheets.
Synthetic biodegradable polymers
There are numerous opportunities for the use of synthetic biodegradable polymers in biomedical applications, particularly in tissue engineering and controlled drug delivery. Degradation is significant in biomedicine for a variety of reasons. Because the polymeric implant degrades, surgical intervention may not be required to remove the implant at the end of its functional life, avoiding the need for a second surgery. Biodegradable polymers can be designed to approximate tissues in tissue engineering, providing a polymer scaffold that can withstand mechanical stresses, provide a suitable surface for cell attachment and growth, and degrade at a rate that allows the load to be transferred to the new tissue. Biodegradable polymers have enormous potential in the field of controlled drug delivery, either as a drug delivery system alone or in conjunction with functioning as a medical device. The chemistry of some polymers, including synthesis and degradation, is reviewed below in the development of biodegradable polymer applications. A description of how proper synthetic controls such as copolymer composition can control properties, special processing and handling requirements, and some commercial devices based on these materials are discussed.
Melt processing of biodegradable polymers can be done using traditional methods such as compression or injection moulding. The need to keep moisture out of the material must be given special consideration. To avoid humidity, the polymers must be thoroughly dried before processing. Because the majority of biodegradable polymers are the result of ring-opening polymerization, there is a thermodynamic equilibrium between the forward polymerization reaction and the reverse reaction that results in monomer formation. It is critical to avoid exceedingly high processing temperatures, which may result in monomer formation during the moulding and extrusion processes. It must be strictly adhered to. Resorbable polymers can be 3D printed as well.

FAQs
What are the top five synthetic polymers?
Polypropylene, polyvinyl chloride, polystyrene, nylon, and Teflon are all examples of plastics.
Is plastic a type of synthetic polymer?
Plastics are synthetic polymers or semi-organic compounds made from oil or petroleum and bind cells using chemicals and condensers. Although polymers occur naturally, plastics are entirely man-made.
What are the benefits of a synthetic polymer?
Desirable Buildings are a significant benefit of Synthetic Polymers. They have high strength, desirable flexibility, resistance, chemical resistance, and other characteristics. The most desired property of synthetic polymers is their resistance to chemical reactions, as well as their resistance to various types of chemical degradation.
