PURPOSE:The titled resin composition capable of providing a molding which scarely undergoes marring and hazing and retains properties such as impact strength, flexural rigidity and high-temperature rigidity, prepared by mixing a specified fiber-reinforced polypropylene resin composition, an amorphous ethylene/propylene copolymer, etc. CONSTITUTION:100pts.wt. resin composition comprising 45-89.5wt% propylene polymer (MI of about 1-50g/10min), 5-20wt% polyethylene (MI of about 0.1- 20g/10min and density >=about 0.94g/cm<3>), 5-40wt% silane-treated mineral fiber (e.g. calcium silicate fiber treated with aminoethyltriethoxysilane) and 0.1-5wt% unsaturated acid-modified polyolefin is mixed with 4-25pts.wt. amorphous ethylene/propylene copolymer and/or 5-80pts.wt. silane-modified nonfibrous inorganic filler (e.g., silane-treated talc).
