PROPYLENE POLYMER COMPOSITION AND ITS INJECTION-MOLDED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a propylene polymer composition and its injection-molded article including nucleating additive, excellent in transparency, having high crystallization temperature and excellent impact resistance. SOLUTION: This propylene polymer composition and its injection-molded article comprises 100 pts.wt. of a propylene polymer including <=0.06 wt.% of aluminum obtained by using a catalyst comprising a transition metal complex of a third to tenth group of the periodic system and 0.001 to 3.0 pts.wt. of the nucleating additive.
