Saturated hydrocarbon polymers, such as, for example, fluorine-containing rubber, siloxane rubber, and ethylene-propylene rubber, are effectively vulcanised by organic peroxides. Owing to the formation of heatresistant carbon-carbon bonds with high energy between the rubber macromolecules, vulcanisates produced using peroxide crosslinking systems possess increased thermal stability and resistance to thermo-oxidative ageing and other effects. This makes peroxide vulcanisation central to the creation of various mechanical rubber goods.

Acrylate rubbers (ARs) and rubber compounds based on them possess a number of valuable properties-high heat, ozone, and oil resistance. They have superior hightemperature resistance to all oil-resistant elastomers, with the exception of fl uorine-containing and fl uorosiloxane rubbers. At the same time, acrylate rubbers are much cheaper. Owing to this combination of properties, mechanical rubber goods based on acrylate rubbers are now being widely used in transport engineering, especially in automobile manufacture [1].

More stringent present-day requirements concerning the service characteristics of mechanical rubber goods has led to the expansion of the range of special-purpose synthetic rubbers becoming the most important direction of scientifi c and technical progress as regards the feedstock base for the production of mechanical rubber goods. These rubbers ensure increased durability of rubber products at high temperatures and on contact with different corrosive media. The aim of the present work was to investigate the resistance of acrylate rubber compounds previously developed by the authors to the action of oils at elevated temperatures.
