POLYOLEFINZUSAMMENSETZUNGEN MIT VERBESSERTEN OPTISCHEN UND MECHANISCHEN EIGENSCHAFTEN |
摘要 |
<p>Novel polyolefin compositions comprising
(A) a first propylene-ethylene random copolymer and
(B) a second propylene-ethylene random copolymer, wherein
the polyolefin composition has an ethylene content CM AB of 1 - 10 wt% and an MFR(AB) of 3 - 20 g/10 min with the proviso that CM AB > CM A and MFR(A)/MFR(AB) > 1.45 and where the polyolefin composition further has a randomness R of the ethylene distribution in the polymer chain of ‰¥ 0.945. Articles made from the novel polyolefin compositions have excellent optical properties even after subjecting them to a heat sterilisation step.</p> |
