Question

Polymer formation from monomers starts by:

• A. condensation reaction between monomers
• B. coordination reaction between monomers
• C. hydrolysis of monomers.
• D. conversion of monomer to monomer ions by protons

Answer 1

The correct option is A condensation reaction between monomers

Addition polymers: These polymers are formed by the repeated addition of the standard molecule which is known as the monomer which forms the polymer. Addition polymers have double and triple bonds. If the monomer used for polymerisation is a single species then the addition polymers are known as homopolymers like polythene and if the monomers are of two different species then the addition polymers are known as copolymers like Buna-S.
Condensation polymers: These polymers are formed by repeated condensation reactions of the bi and tri-functional monomers. In this process small molecules are eliminated like water, alcohol and others. Polymers such as nylon-6,6 is formed by repeated condensation reactions and are considered as condensation polymers.
Among the given options, polymer formation takes place through the process of repeated addition of monomers or when monomers undergo repeated condensation reaction and small molecules are removed.
Thus, the correct option is (a) Condensation reaction between monomers starts the process of polymerisation
