Abstract
PURPOSE: To prepare the titled composition having well-balanced impact strength and rigidity, and especially excellent low-temperature impact strength and gloss, by blending a specific propylene.ethylene random copolymer, a polypropylene, and a polyethylene.
CONSTITUTION: (A) 3W20wt% of a propylene.ethylene random copolymer having an intrinsic viscosity [η] (measured in decaline at 135°C) of 2W10dl/g, propylene content of 30W85mol%, microisotacticity of ≥0.8 defined by the sequence of three propylene units, and boiling cyclohexane insoluble content of ≤10wt%, is mixed with (B) 2W30wt% of a polyethylene, and the mixture is blended with (C) 65W 95wt% of a polypropylene having [η] of 1W4dl/g to obtain 100wt% of the objective composition. Pref. 1W5wt% of the propylene.ethylene random copolymer is further added to the mixture of (A) and (B) together with the (C) component.
