Disclosed herein is a multimodal polymer composition comprising 45 to 75 wt % of a first polymer fraction, 25 to 55 wt % of a second polymer fraction, and from 10-50 phr of an extender oil. The multimodal polymer composition has an overall Mooney viscosity of less than 90 ML(1+4@125&#xb0; C.), and each polymer fraction comprises an ethylene, C-Calpha-olefin, non-conjugated diene polymer, wherein the first polymer fraction has a Mooney viscosity of greater than or equal to about 150 ML(1+4@125&#xb0; C.), the second polymer fraction has a Mooney viscosity from about 20 to about 120 ML(1+4@125&#xb0; C.). A process for making the multimodal polymer composition comprising a process utilizing two or more reactors in series is also disclosed.

Multimodal ethylene-alpha-olefin elastomers and process for making

A rubber composition which in the cured state shows improved adhesion to substrate through hydroxyl-reactive adhesives such as polyurethane comprises a first elastomer such as EPDM which shows generally poor adhesion, a minor proportion of a halogenated elastomer, phenol resin, a curative system for covulcanizing the elastomer, and an aminic substance which catalyses reaction between the resin and isocyanate containing adhesives.
