A series of undrawn and drawn tapes has been prepared from HDPE, as well as, blends consisting of 90% HDPE and 10% ethylene copolymers. The influence of both the molecular irregularity of ethylene copolymers and resultant crystallization behavior on structure and mechanical properties of these blend

A homoisotactic polypropylene (PP) was melt blended with 0-30 wt % of three kinds of polystyrene (PS) with melt flow indexes lower than, similar to, and higher than that of PP. The blends were injection molded at cylinder temperatures of 200-280ΠC, and the structure and properties of the injection m
The effect of time-temperature treatment on the mechanical properties and morphology of polyethylene-polypropylene (PE-PP) blends was studied to establish a relationship among the thermal treatment, morphology, and mechanical properties. The experimental techniques used were polarized optical micros
