A series of notched impact tests were made to polypropylene PP materials of different crystalline morphology through a Ž . certain effective filled nucleating agent 0.1᎐2 wt.% and subsequent heat-treatment. A maximum of impact strength exists at the 0.4 wt.% filled quantity of the nucleating agent.

## Abstract High impact polypropylene (HIPP) was prepared by in situ blending of isotactic polypropylene and ethylene–propylene rubber (EPR) with spherical Ziegler–Natta catalyst. Morphology and pore characteristics of such HIPP were investigated by scanning electron microscope, atomic force micros
## Abstract A sequence of experimental steps was perfected to produce high‐impact modified polypropylene (PP), and to study the influence of particle morphology and rubber content on the reaction kinetics, especially in terms of mass transfer limitations. It was found that after a critical copolyme
