摘要
Supercritical carbon dioxide-assisted extrusion was adopted to prepare polypropylene containing aryl amide nucleating agent. The experimental results showed that supercritical carbon dioxide did not affect the nucleating efficiency of nucleating agent on polypropylene but acted as a carrier to facilitate the dissolution and self-assembly in polymer melts, so as to promote polypropylene crystallize into rich -modification of needle-like crystals with outstanding toughening effect at low temperature.
