POLYPROPYLENE COMPOSITIONS WITH IMPROVED IMPACT RESISTANCE |
摘要 |
The invention concerns polypropylene compositions with improved impact strength adapted for conversion to finished articles by extrusion drawing, extrusion blow-molding or thermoforming characterized in that they contain: (a) 40 to 98% by weight of isotactic polypropylene (b) 2 to 60% by weight of a copolymer of linear low density polyethylene type with a density of up to 0.935, obtained by copolymerizing a mixture of ethylene and one or more upper alpha-olefins, by a copolymerizing process at a pressure below 4.106 Pa, in the absence of any liquid hydrocarbons. |
