ABSTRACT:
Disclosed is a glass fiber-reinforced composition, which comprises (A) 99-40 wt. % of a modified ethylene/propylene block copolymer having a polar monomer content of at least 0.05 wt. %, which is obtained by graft-modifying at least partially a crystalline ethylene/propylene block copolymer, in which the ethylene content is 3-15 wt. %, the melt flow rate is 0.1 to 70 g/10 min, the intrinsic viscosity of the portion soluble in p-xylene at normal temperature is 2.5-6 as measured in decalin at 135.degree. C. and the ethylene content of the portion insoluble in p-xylene at normal temperature is 1.5-10 wt. %, with a polar monomer and an organic peroxide in an extruder, (B) up to 20 wt. % of a polyolefin rubber, and (C) 1 to 45 wt. % of a surface-treated glass fiber. This composition gives a molded article having an excellent rigidity and impact resistance.
