POLYOLEFIN MASTERBATCH BASED ON GRAFTED POLYPROPYLENE AND METALLOCENE CATALYZED POLYPROPYLENE

摘要

The present disclosure provides masterbatch compositions comprising a polypropylene grafted with a grafting monomer selected from maleic anhydride, acrylic acid or other acid or anhydride functional groups that could be grafted to a polypropylene backbone and a metallocene catalyzed polypropylene base resin. Additionally, the present disclosure provides a polymer composition which includes from 0.1 to 10.0 wt.% of the masterbatch composition, and from 50 to 90% of a third polypropylene, and from 5 to 45% of a filler.
