## Abstract The copolymerization of styrene (St) and maleic anhydride (MA) was carried out in supercritical carbon dioxide (SC CO~2~). It was found that St and MA are easy to copolymerize in SC CO~2~ and the conversion can reach 97%, and that very fine and dry powders are obtained. The products wer
