A glass fibre-reinforced polypropylene composition which comprises n 100 parts by weight of a mixture consisting of 95 to 55 parts by weight of a graft polypropylene resin obtainable by graft-polymerising a radically-polymerisable unsaturated compound on to a crystalline polypropylene in a hydrocarbon solvent, in the presence of an organic peroxide catalyst, optionally together with a crystalline polypropylene, and 5 to 45 parts by weight of glass fibres treated with an organic silane compound or an organic titanium compound; n 0.005 to 0.05 parts by weight of calcium stearate; and 0.01 to 0.07 part-by weight of a member selected from alkaline earth metal oxides, hydroxides, basic salts and basic complex salts. |
