Abstract

PURPOSE: The titled composition that is made by mixing 2 kinds of specific crystalline polypropylenes under melting, thus having good moldability without loss of its intrinsically good properties and giving moldings with beautiful surface free from fish eyes.
CONSTITUTION: The objective composition is composed of (A) 40W70wt% of a crystalline propylene homopolymer or copolymer thereof with another α-olefin of 0.6W2.5dl/g intrinsic viscosity and (B) 30W60wt% of a crystalline propylene homopolymer or copolymer thereof with another α-olefin of 2.5W10dl/g intrinsic viscosity, which is twice or more that of component A. The intrinsic viscosity of the total composition is 2W4dl/g.
