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.

1. A polymer composition comprising:
(A) from 0.1 to 10.0 wt. %, based on the total weight of the polymer composition, of a masterbatch composition comprising:
(i) from 1 to 99 wt. %, based on the total weight of the masterbatch composition, of a first polypropylene composition, wherein the first polypropylene composition comprises a polypropylene grafted with a monomer containing acid or anhydride functional groups, and(ii) from 1 to 99 wt. %, based on the total weight of the masterbatch composition, of a second polypropylene obtained by using a metallocene catalyst, (B) from 50 to 90 wt %, based on the total weight of the polymer composition, of a third polypropylene, and (C) from 5 to 45 wt %, based on the total weight of the polymer composition, of a filler.
