高流动性多相聚丙烯
摘要：
根据ISO 1133测定MFR(2.16kg，230℃)大于40g/10分钟的多相聚丙烯树脂包括丙烯均聚物或共聚物基体(A)和分散在该基体中的乙烯-丙烯橡胶相(B)，其中所述多相聚丙烯树脂中含有根据DIN ISO 1628-1和-3测定特性粘度为1.2dl/g或更低的、不溶于25℃的对二甲苯的成分(XCU)以及根据DIN EN ISO 1628-1和-3测定特性粘度为2.0-3.5dl/g的、可溶于25℃的对二甲苯的成分(XCS)，所述不溶于25℃的对二甲苯的成分(XCU)由至少95wt％的丙烯单体单元组成，所述可溶于25℃的对二甲苯的成分(XCS)由50wt％或更多的丙烯单体单元组成，并且根据ISO 6721-7对由所述XCS成分组成的压塑样品由DSC测得的玻璃化转变温度Tg为-42到-30℃。
摘要（英）：

Heterophasic polypropylene resin having an MFR (2.16 kg, 230 DEG C) of more than 40 g/10 min, determined according to ISO 1133 comprising a propylene homo- or copolymer matrix (A) and an ethylene-propylene rubber phase (B) dispersed within the matrix, wherein the heterophasic polypropylene resin has a fraction insoluble in p-xylene at 25 DEG C (XCU) with an intrinsic viscosity of 1.2 dl/g or less, determined according to DIN EN ISO 1628-1 and -3, the fraction insoluble in p-xylene at 25 DEG C (XCU) being composed of propylene monomer units in an amount of at least 95 wt.-%, and a fraction soluble in p-xylene at 25 DEG C (XCS), having an intrinsic viscosity of 2.0 to 3.5 dl/g, determined according to DIN EN ISO 1628-1 and -3 and being composed of propylene monomer units in an amount of 50 wt. -% or more, and having a glass transition temperature Tg as measured by DSC according to ISO 6721-7 at a compression moulded sample consisting of the XCS fraction in the range of - 42 to - 30 DEG C.
