Copolymerization is a chemical process where two or more different types of monomers are combined to form a copolymer. This results in a polymer with unique properties that differ from those of the individual homopolymers made from each monomer alone. There are various methods of copolymerization, including random, block, and graft copolymerization. Each method influences the arrangement of the monomers in the final copolymer, affecting its physical and chemical characteristics, such as strength, flexibility, and resistance to heat or chemicals.
