POLYPROPYLENE OF IMPROVED PROCESSABILITY FOR PRODUCTION OF PIPES

摘要

The present invention relates to a polymer composition, comprising (i) a polypropylene-based matrix which comprises a polypropylene random copolymer prepared by copolymerization of propylene with an olefin comonomer, wherein the amount of olefin comonomer units is within the range of (0.2) wt% to (5) wt%, based on the weight of the polypropylene-based matrix, and (ii) an elastomeric copolymer of propylene and at least one olefin comonomer, the polymer composition having a storage modulus G1 at a loss modulus G"=5 kPa of G'(5 kPa) < (3100) Pa, measured at (22O<SUP>0</SUP>C).
