copolymer
의미: A polymer formed from two or more different types of monomer, resulting in a material with properties distinct from those of either homopolymer alone.
Copolymers are fundamental to modern materials science. By combining different monomers, chemists can tailor mechanical, thermal, and chemical properties for specific applications. Types include random copolymers (monomers in no particular order), alternating copolymers, block copolymers (sequences of each monomer grouped together), and graft copolymers. Familiar examples include styrene-butadiene rubber (SBR) used in car tyres, and ethylene-vinyl acetate (EVA) found in packaging and footwear. The process of forming copolymers is called copolymerisation.
