## Abstract A critical concentration was found for different compositions of UHMWPE/SBPE solutions, at which the concentration dependence of the reduced viscosity changes from low to high power. The critical concentration (__C__~c~) is shifted to a higher value with increasing amount of SBPE in the

High-density polyethylenes with unimodal and bimodal molecular weight distribution have been fractionated according to crystallizability using preparative temperature rising elution fractionation. The molecular structure and thermal properties of the fractions with their whole polymers have been cha
## Abstract An investigation of the influence of the shortβchain branch length on the dynamic fatigue behavior of shortβchain branched polyethylenes (SBPE) is reported. The number of fatigue failure cycles (__N__~f~) increases significantly with increasing branch length at temperatures above the Ξ²β
