POLYOLEFIN COMPOSITION HAVING A HIGH BALANCE OF STIFFNESS AND IMPACT STRENGTH |
摘要 |
A polyolefin composition comprising (percentage by weight): (A) from 40 to 60 % of a broad molecular weight distribution propylene polymer (component A) having a polydispersity index from 5 to 15 and melt flow rate of from 80 to 200 g/10 min (according to ASTM-D 1238, condition L); and (B) from 40 to 60 % of a partially xylene-insoluble olefin polymer rubber (component B) containing at least 65 % by weight of ethylene; the IVS/IVA ratio between the intrinsic viscosity (IVS) of the portion soluble in xylene of the polyolefin composition at room temperature and the intrinsic viscosity (IVA) of component (A) ranging from 2 to 2.5, both values on intrinsic viscosity being measured in tetrahydronaphthalene at 135 DEG C. Said composition finds application in automotive field.
