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 200-280ЊC, and the structure and properties of the injection m

## Abstract In this work, the effect of a nucleating agent on the crystallization structure of an injection‐molded bar of a polypropylene random copolymer (PPR) with sorbitol derivatives [1,2,3,4‐dibenzylidene sorbitol (DBS)] has been studied. The results show that pure PPR forms a simple skin–core

In this work, impact copolymer polypropylene (ICPP) was fractionated into 4 fractions. ICPP and the 4 fractions were studied using Fourier transform infrared and 13 C nuclear magnetic resonance analysis. The results demonstrate that fraction A is ethylene-propylene rubber, fraction B is ethylene-pro
