Glass fiber reinforced polypropylene compositions comprising crystalline e-p block copolymer graft modified with itaconic anhydride

摘要

A glass fiber reinforced polypropylene composition comprising 50 to 85% by weight of a crystalline ethylene-propylene block copolymer which has been graft-modified with itaconic anhydride, 5 to 45% by weight of a glass fiber and 3 to 20% by weight of a polyolefin rubber which has been graft-modified with an unsaturated carboxylic acid (100% by weight in total).
