Copolymers are materials made from two or more different types of monomers, which are the building blocks of polymers. By combining different monomers, copolymers can exhibit unique properties that are not found in homopolymers, which consist of only one type of monomer. This versatility allows copolymers to be tailored for specific applications, such as in plastics, elastomers, and fibers. There are various types of copolymers, including block copolymers, random copolymers, and alternating copolymers. Each type has a distinct arrangement of monomers, influencing its physical and chemical properties. Copolymers are widely used in industries like automotive, packaging, and biomedical engineering due to their customizable characteristics.
