Abstract Styrene and 4-chloromethylstyrene copolymer is synthesized using different ratios of styrene (St) and
4-chloromethylstyrene (CMS) by free radical copolymerization. The impact of different feed ratios on its copolymer composition is
studied. The content of chloromethyl in copolymers is calculated and the heat resistance is analyzed by TGA.
