Synthesis and properties of polyethylene composites with natural zeolites

Two types of immobilized catalysts active in ethylene polymerization were prepared on the basis of natural zeolite-containing minerals. The catalysts were composed of anchored alkylaluminoxanes and vanadium oxytrichloride and. the anchored compounds of vanadium and Al(i-Bu 3 ) or AlEt 2 Cl, The kinetics of ethylene polymerization in the presence of zeolites was studied, and the mechanical and tribological properties of the resulting PE composites were investigated. The polymerization-filled composite material based on UHMPE and natural zeolites that combine enhanced wear-resistant properties with low friction coefficient and high impact strength were developed.
