Title:
POLYPROPYLENE RESIN COMPOSITION AND POLYPROPYLENE RESIN MOLDED PRODUCT
Document Type and Number:
Japanese Patent JP2021054930
Kind Code:
A
Abstract:
To provide a polypropylene resin composition capable of obtaining a polypropylene molded product having excellent abrasion resistance and weather resistance by using a graft copolymer with excellent extrusion stability which includes a polypropylene-based segment and a polystyrene-based polymer segment.SOLUTION: There is provided a polypropylene resin composition containing a polypropylene resin (A) and a graft copolymer (B). The graft copolymer (B) is a graft copolymer obtained by reacting a monomer component containing a polypropylene resin and a styrene-based monomer with a vinyl-based monomer having a peroxide bond. The polypropylene resin has an MFR of 0.5 to 7 g/10 min under a load of 2.16 kg at 230°C. A mass ratio of the polypropylene resin to the monomer component containing the styrene-based monomer (the polypropylene resin/the monomer component containing the styrene-based monomer) is 60/40 to 90/10. The graft copolymer (B) has a content of 1 pts.mass or more and 25 pts.mass or less based on 100 pts.mass of the polypropylene resin (A).SELECTED DRAWING: None
