Abstract

High-temperature oil-resistant elastomers are prepared from butadiene alkenylpyridine copolymers, butadiene-acrylate copolymers, and copolymers of butadiene with 1,3-dienes containing fluorine. The unsaturated olefinic backbone and pendant unsaturation derived from the hydrocarbon diene of each of the copolymers is hydrogenated to a high degree by a catalyst which improves the heat resistance of the copolymer without hydrogenation of the polar groups thereof which would lower the oil-resistance of the copolymer. A complexing agent for the hydrogenation catalyst prevents poisoning of the catalyst by the polar groups of the copolymers thereby enabling the catalyst to complex with unsaturated sites along the olefinic copolymer backbone to achieve high levels of hydrogenation thereof.
