PELLET COMPRISING PROPYLENE-BASED POLYMER COMPOSITION, MODIFIER FOR THERMOPLASTIC POLYMER, AND METHOD FOR MANUFACTURING THERMOPLASTIC POLYMER COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a polymer composition excellent in transparency, low-temperature impact resistance, mechanical properties (flexibility or rigidity, etc.), and also heat resistance, and a molded product comprising the composition.;SOLUTION: The propylene-based polymer composition comprises: (A) 40-95 pts.wt. of a propylene-based polymer; and (B) 60-5 pts.wt. of a propylene/ethylene/α-olefin copolymer comprising 84-50 mol% of constitutional units derived from propylene, 15-30 mol% of constitutional units derived from ethylene, and 1-20 mol% of constitutional units derived from α-olefin having 4-20 carbon atoms (provided that the total of (A) and (B) is 100 pts.wt.).;COPYRIGHT: (C)2012,JPO&INPIT
