摘要：
A glass-fiber reinforced polypropylene composition having superior adhesion of glass fibers therein, stiffness, high-impact properties and molding properties is provided, which composition comprises a graft polypropylene resin obtained by graft-polymerizing a radically polymerizable unsaturated compound onto a crystalline polypropylene resin with an organic peroxide catalyst in a hydrocarbon solvent or a blend of the graft polypropylene with a crystalline polypropylene resin, glass fibers treated with an organic silane or titanium compound, Ca stearate and an alkaline earth metal compound, the respective quantities of the above components being specified.
