In the 1960s, the German company Hoechst first developed successfully and realized industrial production. China began to develop chlorinated polyethylene from the late 1970s. It was first developed by the Anhui Institute of Chemical Industry to successfully develop the "aqueous phase suspension synthesis CPE technology", and has successively built 500-1000t/a production facilities of different scales in Wuhu, Anhui, Taicang, Jiangsu and Weifang, Shandong. In the early 1990s, Shandong Weifang Chemical Plant imported 6000t/a CPE complete sets of production equipment from Germany. The production of resin-type chlorinated polyethylene at the beginning is mainly used as an impact modifier for PVC and a flame retardant modifier for engineering plastics such as ABS.
