Draw the structure of the polymer formed by chain-growth polymerization of each monomer.

(a.)

(b.)

(c.)

(d.)

Chain-growth polymerization is a chain reaction that converts an organic starting material, usually an alkene, to a polymer via a reactive intermediate—a radical, cation or anion.

Initiator is required to start the polymerization, then chain propagation takes place and finally, termination occurs when two radicals cartels to form bonds.

In this question, 4 monomers are given i.e.,vinylidene fluoride, diethylorthoformate, crotonamide, and cyclohexymethanolate form polymers.

a.

Vinylidene fluoride is polymerized by chain growth polymerization to form polyvinylidene fluoride.

Formation of polyvinylidene fluoride

b. Diethylorthoformate is polymerized by chain-growth polymerization to form polydiethylorthoformate.

Formation of polydiethylorthoformate

c. Crotonamide is polymerized by chain growth polymerization to form polycrotonamide.

Formation of polycrotonamide

d. Cyclohexymethanolate is polymerized by chain growth polymerization to form polycyclohexymethanolate.

Formation of polycyclohexymethanolate
