根据应用范围的不同，PVC可分为：通用型PVC树脂、高聚合度PVC树脂、交联PVC树脂。通用型PVC树脂是由氯乙烯单体在引发剂的作用下盖土网 防寒布 麻绳 油麻绳 麻刀 沥青麻绳 静压造型线 自动浇注机 铸铁拍门 钢制拍门 玻璃钢拍门聚合形成的；高聚合度PVC树脂是指在氯乙烯单体聚合体系中加入链增长剂聚合而成的树脂；交联PVC树脂是在氯乙烯单体聚合体系中加入含有双烯和多烯的交联剂聚合而成的树脂。
According to the different application range, PVC can be divided into: General PVC resin, high polymerization degree PVC resin, cross-linked PVC resin. General purpose PVC resin is formed by polymerization of vinyl chloride monomer under the action of initiator; high degree of polymerization PVC resin refers to the resin polymerized by adding chain growth agent in vinyl chloride monomer polymerization system; cross linked PVC resin is polymerized by adding crosslinker containing diene and polyene in vinyl chloride monomer polymerization system.
