POLYSULFONE COPOLYMER WITH EXCELLENT HEAT RESISTANCE AND CHEMICAL RESISTANCE, AND METHOD FOR PREPARING SAME

摘要

The present invention relates to a polysulfone copolymer with excellent heat resistance and chemical resistance, and a method for preparing the same and, more specifically, to a polysulfone copolymer and a method for preparing the same, wherein the polysulfone copolymer comprises, as repeat units, a sulfone-based compound, and an anhydrosugar alcohol, which is a biogenic material, and thus the polysulfone copolymer can solve a problem of an exhaustion of petroleum resources, which are limited resources; does not emit carbon dioxide regardless of the disposal after use, and thus is eco-friendly; and has significantly improved heat resistance and chemical resistance compared with existing polysulfone copolymers.
