Claim:
1. A process to produce an elastomeric composition, said process comprising: blending at least one non-fibril cellulose ester, at least one non-nitrile primary elastomer, and at least 70 phr of one or more fillers to produce said elastomeric composition, wherein at least a portion of said blending occurs at a temperature exceeding the Tg of said at least one non-fibril cellulose ester, wherein said elastomeric composition exhibits a Mooney viscosity at 100° C. as measured according to ASTM D1646 of not more than 110 AU, wherein a starch is absent during said blending, wherein at least a portion of said at least one non-fibril cellulose ester is dispersed in said at least one non-nitrile primary elastomer, wherein said at least one non-nitrile primary elastomer forms a continuous phase and at least a portion of said at least one non-fibril cellulose ester forms a dispersed phase; and wherein said elastomeric composition exhibits a molded groove tear as measured according to ASTM D624 of at least 130 lbf/in.
