Title:
PROPYLENE-BASED POLYMER COMPOSITION
Document Type and Number:
Japanese Patent JP3487678
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a propylene-based composition comprising a propylene-based polymer, an olefinic elastomer and a specific polar group-containing olefinic copolymer and excellent in balance between rigidity and impact resistance, also excellent in coating property and solvent resistance of coated film and useful for interior material, etc., for automobiles.
SOLUTION: This propylene-based polymer composition comprises (A) a propylene-based polymer, (B) an olefinic elastomer and (C) a polar group- containing olefinic copolymer obtained by heating a modified olefinic copolymer (C-1) obtained by grafting a carboxyl or acid anhydride group-containing unsaturated compound a copolymer of a propylene with a 2C or 4-20C α-olefin (M1), a copolymer of ethylene with 3-20CM1 or a copolymer of 2-20C M1 with a non-conjugated diene and having ≤50% degree of crystallization and an amino compound (C-2), and contains the component C in an amount of 1-40 pts.wt. based on 100 pts.wt. component C.
