1.	The synthesis of which of the following polymers involves the repeated loss of small molecules?(a) Polythene(b) Buna-S(c) Buna-N(d) Nylon-6,6This question was addressed to me during an internship interview.This question is from Classification of Polymers in chapter Polymers of Chemistry – Class 12
Answer» Correct answer is (d) Nylon-6,6 For explanation I would say: CONDENSATION polymers are formed by the repeated condensation reaction between two different bi-functional or tr-functional monomeric units, along with the loss of small molecules like WATER, ALCOHOL, HCl, etc. Nylon-6,6 is formed by the condensation of hexamethylene DIAMINE and adipic acid, RESULTING in loss of water molecules.
