POLYOLEFIN COMPOSITION WITH IMPROVED CHARACTERISTIC

摘要

PROBLEM TO BE SOLVED: To provide a polyolefin composition with good impact strength and transparency. SOLUTION: The polyolefin composition comprises (a) 85-98 wt.% based on the total weight of the composition of a hetero-phase propylene/α-olefin copolymer comprising a polymer or copolymer of propylene containing 0-15 mol% of theα-olefin as a matrix polymer and a propylene/α-olefin rubbery copolymer containing 20-80 mol% of theα-olefin, and (b) 15-2 wt.% based on the total weight of the composition of an ethylene homopolymer having a density lower than 0.920 g/cm3. The polyolefin composition has good impact strength and transparency. COPYRIGHT: (C)2008,JPO&INPIT
