THE INFLUENCE OF POLYMERIZATION DEGREE ON THE PROPERTIES OF ULTRAHIGH MOLECULAR WEIGHT POLYETHLENE

摘要

Polyethylene (PE) takes first stand among all plastic materials due to the valuable technical properties and low price of raw material [1]. Low density PE (LDPE) and high density PE (HDPE) are prevailing. There is conventional scale of HDPE on its molecular weight. In our country PE is classified on standard HDPE (molecular weight is 300 000 - 700 000) and ultrahigh molecular weight PE (UHMWPE) with molecular weight more than 1 000 000 [2].
