Abstract
Hydrogenated butadiene-nitrile Therban rubbers with acrylonitrile content of 34 to 49% and unsaturation degree of 0.9 to 6.0% and their mixes were studied upon exposure to aggressive media and elevated temperatures in the range of 125 to 150 C. Rubbers with peroxide and sulfur-peroxide vulcanization systems showed a high level of polyfunctional properties (fuel, oil и heat resistance). The dependences of functional properties of rubbers on acrylonitrile content and unsaturation degree in rubber macromolecules were revealed.
