Graft polymers of functionalized ethylene-alpha-olefin copolymer with polypropylene, methods of preparation, and use in polypropylene compositions

摘要

Graft polymer comprising functionalized ethylene-­alpha-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.
