Abstract

Abstract: Impregnation of isotactic polypropylene （iPP） with nucleating agent （NA21） using supercritical carbon dioxide as the swelling agent at different temperature and pressure and its non-isothermal crystallization kinetics were investigated. The results showed that NA21 was dispersed at a nanometer-scale in the PP matrix, resulting in the formation of different types .of crystal phases of iPP and the enhancement of its mechanical properties.

Key words: supercritical carbon dioxide, polypropylene, nucleating agent, mechanical performance
