The isothermal and nonisothermal crystallization kinetics of nonnucleated and nucleated isotactic polypropylene ( iPP ) were investigated by DSC and a polarized light microscope with a hot stage. Dibenzylidene sorbitol ( DBS ) was used as a nucleating agent. It was found that the crystallization rat

A series of notched impact tests were made to polypropylene PP materials of different crystalline morphology through a Ε½ . certain effective filled nucleating agent 0.1α2 wt.% and subsequent heat-treatment. A maximum of impact strength exists at the 0.4 wt.% filled quantity of the nucleating agent.
## Abstract The effects of ultrasonic irradiation on crystallization behavior of polypropylene (PP)βloaded fillers with nucleating activities, such as sodium benzoate, talc (P), talc (A), and mica, are examined. DSC and WAXD analyses demonstrate that the crystalline structure of PP is changed throu
