Notes:
The crystallinity, density, dynamic mechanical properties, (25 to 250°C, 11 Hz), and tensile properties at 25°C have been studied for two mixtures of ultrahigh-molecular-weight linear polyethylene (Mw = 2.0 × 106), abbreviated UHMWLPE, and moderate-molecular-weight linear polyethylene (Mw = 5.7 × 104), abbreviated LPE. These mixtures, which covered the entire composition range, had been prepared with differing solvent-thermal histories. An enhancement of both crystallinity and density and an obvious synergism in tensile properties were observed for quenched films made from the mixture in which both components had been co-dissolved. The data indicate that UHMWLPE and LPE can cocrystallize under given circumstances.
