What polymer is formed by the radical polymerization of each monomer?

(a.)

(b.)

When free radicals act as building blocks and get added up to form a polymer by involving various mechanisms, it is known as radical polymerization.

Radical polymerization is one of the most common way of making polymers.Initiation, propagation, and termination are the three vital steps for radical polymerization.

A double bond is present in methyl methacrylate. During the chain-growth polymerization of methyl methacrylate, the double bond vanishes and becomes a single bond. The monomers join to form a large polymer chain.

Methoxy group and other atoms remain the same during polymerization.

A double bond is present in methacrylonitrile. During the chain-growth polymerization of methacrylonitrile, the double bond vanishes and becomes a single bond. The monomers join to form a large polymer chain.

The nitrile group remain the same during polymerization.
