Abstract:
A polyolefin composition comprising (percentage by weight): (A) from 60 to 85% of a broad molecular weight distribution propylene polymer (component A) having a polydispersity index from 5 to 15 and melt flow rate of from 20 to 78 g/10 min (according to ASTM-D 1238, condition L); and (B) from 15 to 40% of a partially xylene-soluble olefin polymer rubber (component B) containing at least 65% by weight of ethylene. Said composition finds application in automotive field.
