A method of improving the surface characteristics of a molded article made from a composition comprising a polypropylene resin, an engineering plastic and a fuctionalized polyolefin resin containing at least one member selected from among a monomer containing a carboxyl, carboxylic ester, or acid anhydride group, an epoxidized monomer, a hydroxylated monomer, an aminated monomer, an alkenyl cyclic imino ether derivative and a poly-functional monomer, said composition optionally containing an inorganic filler or a rubbery substance, without detriment to the excellent properties thereof, such as rigidity, impact resistance, heat resistance, dimensional stability and processability, said method comprising applying an ultraviolet radiation with a wavelength of 300 nm or less thereto. |
