摘要：

Microporous polypropylene films were produced from nucleated and non-nucleated melt-blends of isotactic polypropylene (iPP) and dotriacontane (C32H66) using non-isothermal thermally-induced phase separation. Adipic acid was used as the nucleating agent. The morphology of these microporous iPP films as determined by thermal optical microscopy and scanning electron microscopy is reported. The effect on film structure of diluent crystallization is also shown.
