Abstract:
A propylene/ethylene/1-hexene terpolymer containing from 1.0 wt% to 2.5 wt %, of ethylene derived units and from 2.0 wt % to 4.0 wt % of 1-hexene derived units, the sum of the amounts of propylene, ethylene and 1-.hexene derived units being 100, having the following features: a) the amount (Wt %) of 1-hexene (C6) and the amount (Wt %) of ethylene (C2) fulfil the following relation: C2
Abstract:
A process for producing polyolefin articles comprising an ethylene-vinyl alcohol copolymer, wherein the polyolefin component is melted and mixed with the ethylene-vinyl alcohol copolymer in the presence of a stabilizing composition comprising: a) one or more acid scavengers in amounts equal to or higher than 300 ppm by weight with respect to the weight of the polyolefin component; and b) one or more phenolic antioxidants in amounts equal to or higher than 1100 ppm by weight with respect to the weight of the polyolefin component.
Abstract:
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 1.5 µm. 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.
