Abstract
An elastomer composition, including: at least one elastomer; a plasticizer which includes at least one polymeric material having a weighted average molecular weight of (Mw) of 500 to 1,000,000, formed from at least one ethylenically unsaturated monomer, and a curing agent, wherein the at least one polymeric material is substantially permanent within the elastomer. The subject elastomer compositions have enhanced plasticity and processability without attendant migration, heat or solvent extraction and compatibility problems.
