Class 12 NCERT Solutions Chapter 15 – Polymers
This chapter includes the topics – the terms Monomer, Polymer, Polymerisation. Classification of Polymers based on source: Natural polymers, Semi-synthetic polymers, synthetic polymer. Classification of polymers based on structure: Linear Branched-chain, Cross-linked or Network Polymers. Classification of polymers based on the mode of polymerization: Addition polymers, Condensation polymers.
Classification of Polymers based on Molecular Forces:
Elastomers, Fibres, Thermoplastic and Thermosetting, Sorts of polymerization. The molecular mass of polymers. Biodegradable polymers. Two Greek words combine to make the term ‘polymer’. In Greek, ‘poly’ means many, and ‘mers’ means part or unit. it’s also mentioned as macromolecules. Samples of polymers are Butadiene, Buna – N, etc. Homo-polymers and Copolymers are two sorts of polymers that are supported their repeating structural unit. A chemical change to supply a chain-like structure or network of molecules called polymer by combining monomers is named polymerization. There are two types of polymerization reactions:
Addition polymerization occurs in three steps:
Step 1: Chain initiation
Step 2: Chain propagation
Step 3: Chain termination
Condensation polymerization: Also called step-growth polymerization
This was the introduction to this chapter. You can go in-depth with the help of NCERT Solutions. Along with NCERT sample questions, one must solve previous year questions and participate in a mock test to qualify for the CBSE Class 12 board exam with good marks.
