Abstract:
1. A multimodal polymer composition comprising: a) 45 to 75 wt % of a first polymer fraction comprising ethylene, a C b) 25 to 55 wt % of a second polymer fraction comprising ethylene, a C c) from about 10 phr to about 50 phr of an extender oil which is a liquid at 25° C., wherein the multimodal polymer composition has a number average molecular weight of from about 60,000 to about 350,000 g/mol, and a Mooney viscosity of less than 90 ML(1+4@125° C.); and wherein the diene in each fraction is independently selected from the group consisting of 5-ethylidene-2-norbornene (ENB), dicyclopentadiene (DCPD), norbornadiene, 5-vinyl-2-norbornene (VNB), divinylbenzene (DVB), and combinations thereof.
