GRAFT POLYMERS OF FUNCTIONALIZED ETHYLENE-ALPHA-OLEFIN COPOLYMER WITH POLYPROPYLENE, METHODS OF PREPARATION, AND USE IN POLYPROPYLENE COMPOSITIONS

摘要

Graft polymer comprising functionalized ethylenealpha-olefin copolymer having polypropylene grafted thereto through one or more functional linkages, the process for making the graft polymer comprising combining the functionalized ethylene-alpha-olefin with maleated polypropylene, the use of the graft polymer for improving the impact properties of polypropylene compositions, and improved polypropylene blends.
