👉 In chemistry, a copolymer is a polymer that contains two or more different types of monomers. These different types can be either linear or branched. Copolymers are formed when two or more different types of monomers are linked together by an appropriate chemical bond. The resulting compound has the same molecular structure as the original, but with different properties due to their specific arrangement and bonds. For example, in a copolymer made from ethylene glycol (Epoxy)
