PROPYLENE POLYMER COMPOSITIONS |
摘要 |
<p>A propylene composition comprising (percent by weight): A) 70%-95%, of a propylene homopolymer having a Polydispersity Index (P.I.) value of from 4.6 to 10, a fraction insoluble in xylene at 25 °C, higher than 90 %, and MFR L (Melt Flow Rate according to ISO 1133, condition L, i.e. 230°C and 2.16 kg load) from 47 to 90 g/10 min; B) 5%-30%, of a copolymer of propylene containing from 40% to 34.5% extremes included of ethylene derived units; the composition having an intrinsic viscosity of the fraction soluble in xylene at 25 °C comprised between 3 and 5 dl/g.</p> |
