    • Copolymers of ethylene and α-olefins are provided having (a) a density (D) in the range 0.900-0.940 g/cm3, (b) a melt index MI2 (2.16 kg, 190° C.) in the range of 0.01-50 g/10 min, (c) a melt index MI2 (2.16 kg, 190° C.) and Dow Rheology Index (DRI) satisfying the equation [DRI/MI2]>2.65, and (d) a Dart Drop Impact (DDI) in g of a blown film having a thickness of 25 μm produced from the copolymer satisfying the equation DDI≧1900×{1−Exp[−750(D−0.908)2]}×{Exp[(0.919−D)/0.0045]}. The copolymers may suitably be prepared by use of metallocene catalysis and are preferably prepared in multistage processes earned out in loop reactors in the slurry phase. The copolymers exhibit long chain branching as defined by Dow Rheology Index (DRI) and exhibit unexpected improvements in mechanical properties, in particular dart drop impact, when extruded into blown films.
    • 提供乙烯和α-烯烃的共聚物,其具有(a)密度(D)在0.900-0.940g / cm3范围内,(b)熔体指数MI2(2.16kg,190℃)在0.01- 50g / 10min,(c)满足方程[DRI / MI2]> 2.65的熔体指数MI2(2.16kg,190℃)和Dow流变学指数(DRI),和(d)Dart Drop Impact )满足式DDI≥10000×{1-Exp [-750(D-0.908)2]}×{Exp [(0.919-D)/0.0045)的共聚物的厚度为25μm的吹塑薄膜 ]}。 共聚物可以适当地通过使用茂金属催化制备,并且优选以在淤浆相中的环管反应器中获得的多阶段方法制备。 共聚物表现出由Dow Rheology Index(DRI)定义的长链支化,并且当挤出成吹塑薄膜时,其机械性能特别是飞镖降落冲击表现出意想不到的改进。
