A Critical Evaluation of Polypropylene Impact Copolymer Morphology
Abstract: In order to improve Polypropylene (PP) impact strength, the process of copolymerizing propylene with ethylene is being used. Polypropylene copolymer is essentially a rubber-toughened material consisting of polypropylene homo-polymer matrix in which ethylene-propylene rubber (EPR) is distributed. The overall impact behavior of the copolymer is solely controlled by the rubber morphology and its distribution in polypropylene matrix, which plays a critical role on crystallinity. Even a similar impact grade polypropylene …
