Advances in the catalytic polymerization of ultra-high molecular weight polyethylene

Ultra-high molecular weight polyethylene(UHMWPE) is a linear structural thermoplastic engineering plastic with excellent properties such as impact resistance,abrasion resistance, corrosion resistance and adhesion resistance. Advances in the research of catalytic polymerization of UHMWPE were reviewed. The properties and research background of UHMWPE were briefly summarized. Different kinds of catalysts for the catalytic polymerization of UHMWPE were discussed in detail. Furthermore,the synthesis method of a disentangled UHMWPE with supported catalyst was also introduced. The future research of the catalysts used for the synthesis of UHMWPE was prospected.
