摘要：Disclosed is a method for preparing copolymers of styrene and maleimide byimidization-extrusion of copolymers of styrene and maleic anhydride using a supercriticalfluid. The method can be performed at a lower temperature compared to a conventionalmethod and can remove residual amines and by-products with ease, and thus can providecopolymers of styrene and maleimide having excellent optical properties, thermalproperties and mechanical properties.
