摘要: A polypropylene-based composite resin composition in which: (1) the complex viscosity .eta.* as measured at 190~C and an angular frequency (.omega.) of 0.1 rad/s is 2,000 Pa.cndot.s or higher; (2) storage moduli shear G'100, G'10, G'0.1, G'0.01 90~C frequencies 100, 10, 0.1, 0.01 respectively satisfy following relationships (I) (II); log(G'100)-log(G'10)>=0.6 log(G'0.1)-log(G'0.01)<=0.4 (II) (3) modulus G'0.0251 0.0251 60 Pa higher. Even when injection-molded a shortened molding cycle time, less apt to cause failures such short shot, burrs, surface adhesion failures, deformation, legginess.
