In the preparation of which of the following, the elimination of small molecules such as water, alcohol, hydrogen chloride, etc. take place

condensation polymers are those which are formed by repeated condensation reaction between two or more different bi-functional or tri-functional monomeric units. In these polymerization reactions, the loss of small molecules such as water, alcohol, hydrogen chloride, etc. take place. The examples are terylene, Bakelite, (dacron), nylon 6, 6,
