What are the three methods of accomplishing this process polymerization?

The three primary methods of polymerization are addition polymerization, condensation polymerization, and copolymerization. Addition polymerization involves the reaction of monomers with unsaturated bonds, resulting in the formation of long-chain polymers without the release of byproducts. Condensation polymerization occurs when monomers join together, releasing small molecules like water as byproducts. Copolymerization combines two different types of monomers to create a polymer with distinct properties.
