ABSTRACT:
Curable and cured elastomer compositions having approved mold release and methods for their preparation are provided. The elastomer compositions comprise an elastomer, a metal salt of an .alpha., .beta.-ethylenically unsaturated compound, an organic peroxide, and a fatty acid metal salt. The invention provides for improved mold release by the incorporation of the fatty acid metal salt into the elastomer composition, at high levels, without a loss in cured properties of the elastomer.
