  • Publication number: 20120165440
    Abstract: The present invention aims to provide a multimodal polymer of propylene comprising a matrix of semicrystalline polymer and a rubber (D) dispersed in said matrix, the multimodal polymer comprising units derived from propylene of from 85 to 99% by weight and units derived from ethylene or C4 to C10 alpha-olefins of from 1 to 15% by weight. The multimodal polymer has a fraction soluble in xylene XS at a temperature of 25° C. of from 7 to 16% by weight, a melt flow rate MFR2 of from 0.05 to 5 g/10 min, a polydispersity index PI of from 3.5 to 30, and a tensile modulus TM and XS meeting the relationship TM?2375?46.2·XS. Furthermore, the present invention aims to produce the above-mentioned multimodal polymer in a process comprising several reaction steps or zones. The compositions comprising the multimodal polymer of propylene have excellent stiffness combined with good impact strength at a low temperature.
