Polypropylene-based resin composition, process for producing the same and injection molded article

A polypropylene-based resin composition comprising 0.5 to 10% by weight of a propylene-based polymer component (A1) obtained by polymerizing a monomer mainly composed of propylene, having an intrinsic viscosity [eta]A1 measured in. tetralin at 135° C. of 5 dl/g or more and a melting peak temperature...

Beschreibung
Zusammenfassung:	A polypropylene-based resin composition comprising 0.5 to 10% by weight of a propylene-based polymer component (A1) obtained by polymerizing a monomer mainly composed of propylene, having an intrinsic viscosity [eta]A1 measured in. tetralin at 135° C. of 5 dl/g or more and a melting peak temperature TmA1 measured by a differential scanning calorimeter of 130 to 160° C., and 90 to 99.5% by weight of a propylene-based polymer component (A2) obtained by polymerizing a monomer mainly composed of propylene, having an intrinsic viscosity [eta]A2 measured in tetralin at 135° C. of less than 5 dl/g.
