Glass fiber reinforced polyolefin resin composition
 Disclosed is a glass fiber reinforced polyolefin resin composition comprising 15-80% by weight of polypropylene, 20-60% by weight of polybutene-1 and 5-60% by weight of glass fiber. This resin composition is excellent in the balance of impact strength, stiffness, heat distortion temperature, surface hardness and processability. When this composition is molded, the molded products have no surface roughness and no color shade and have good appearance. The properties are further improved when a modified polyolefin alone or together with a crystal nucleating agent are added.
