摘要:
A polypropylene composition comprising 100 parts by weight of a crystalline propylene polymer having a molecular weight distribution (Mw/Mn) of less than 5.0 and from 0.0001 to 1.0 part by weight of a crystal nucleating agent, the composition having a crystallization temperature at least 1.5.degree. C. higher than the crystallization temperature of the crystalline propylene polymer.
