Being the polyolefine type resin constituent which consists of the polyolefine type resin constituent

摘要

PROBLEM TO BE SOLVED: To provide a polyolefin resin composition and film or sheet made from the same excellent in blanching retardation and processability capable of calendering. ;SOLUTION: This resin composition is produced by mixing 100 pts.wt. of polypropylene and 10-800 pts.wt. of polyethylene where the MFR of polypropylene is 1-10g/10min, the polyethylene has (Mw/Mn) of ≤3, density of ≥0.870g/cm³ and 1.0-5g/10min of MFR, extruding with radical generator, mixing the extruded product with antioxidant and extruding. The resin composition is modified to have the ratio of (MFRa) before the reaction to (MFRb) after the reaction in the range of 1(MFRa)/(MFRb) ≤3.;COPYRIGHT: (C)1997,JPO
