Abstract

The possibility of heterogenization of a polymer system by using new post-metallocene catalytic systems comprising phenoxy-imine titanium halide complexes with different ligand environments modified by oxyallyl groups was studied with the aim of decreasing sticking of the reactor powders of ultra-high-molecular-weight polyethylene (UHMWPE RPs) suitable for solid-phase processing. The effective use of selfimmobilizing systems for the manufacture of UHMWPE RPs with reduced sticking to the reactor walls and the stirrer, but with somewhat reduced strength of the UHMWPE RP-based articles is shown.
