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