摘要 |
<p>Polypropylene compositions, particularly suited for preparation of stretched/oriented articles, especially for injection stretch blow moulded bottles, comprising: A) one or more propylene homopolymers or propylene copolymers or their mixtures; B) from 500 to about 1500 ppm by weight of talc in form of particles having average particle diameter of equal to or less than 1.5μm. Said compositions display higher crystallization temperature with respect to the same polyolefin (A) without addition of (B), while keeping good levels of transparency, particularly when (A) is or comprises a random polymer.</p> |
