PROPYLENE-BASED BLOCK COPOLYMER RESIN COMPOSITION, PRODUCTION METHOD THEREOF, AND FOAM-MOLDED ARTICLE |
摘要 |
PROBLEM TO BE SOLVED: To provide a propylene-based block copolymer resin composition having high fusion property preferable for foam molding and high mechanical strength during foam molding. SOLUTION: This propylene-based block copolymer resin composition is a resin composition comprising: 0.01 to 5.0 parts by weight of an ethylene polymer (A) having an intrinsic viscosity ([η]) measured in tetralin of 135°C of 15 to 100 dl/g; and 100 parts by weight of a propylene-based block copolymer (B) comprising 30 to 95% by weight of a propylene polymer (B-1) and 5 to 70% by weight of an olefin random copolymer (B-2), characterized in that the ratio of the weight average molecular weight (Mw) relative to the number average molecular weight (Mn) (these molecular weights are measured by a GPC method) (Q value: Mw/Mn) is 10 to 20. Provided are also a production method of the resin composition and a foam-molded article. COPYRIGHT: (C)2009,JPO&INPIT
