聚氯乙烯(PVC)是一种应用广泛的高分子材料,由VCM聚合而成,每个PVC聚合体是由约500～1500个VCM组成。PVC的生产始于本世纪三十年代的德国。我国于1959年开始生产,全世界PVC的产量约1200万吨/年(1981)。
Polyvinyl chloride (PVC) is a widely used polymeric material, polymerized from VCM, each of which is comprised of about 500 to about 1500 VCM. The production of PVC began in Germany in the thirties of this century. China started production in 1959 and the world’s PVC production is about 12 million tons / year (1981).
