摘要：
Altering the polymer's molecular structure involves the introduction of long chain branching by the use of single-site catalyst (SSC) systems in polymerization. However, the intrinsic mechanism whereby distortions disappear was not yet established. The preliminary results on the use of small amounts of ultrahigh molecular weight polyethylene (UHMWPE) as a possible route for the elimination of distortions in metallocene polyethylenes (mPEs) are presented.
