发明名称 Polypropylene resin composition and process for producing the same
摘要 A polypropylene resin composition comprising (a) 100 parts by weight of a resin composition, which contains 51 to 99% by weight of a propylene polymer and 1 to 49% by weight of an ethylene polymer having a density of 0.85 to 0.93 g/cm3, and (b) 0.001 to 0.5 part by weight of a metal salt defined by a specific chemical formula; and a process for producing such a polypropylene resin composition, comprising the steps of (1) mixing 1 to 100 parts by weight of the metal salt with 100 parts by weight of the propylene polymer and/or the ethylene polymer, thereby producing a master batch, and (2) mixing the master batch with a mixture containing the propylene polymer and the ethylene polymer.
