Influence of Propylene Units Stereoregularity in Modified Ethylene-Propylene-Diene Elastomers on the Ozone Resistance of Covulcanizates with Acrylonitrile-butadiene Rubbers
The modification of ethylene–propylene–diene elastomers via the addition of fragments of an accelerating agent to improve their compatibility with acrylonitrile-butadiene rubbers and to reduce the rate of ozone degradation of the polydiene matrix is efficient only in the case of low stereoregularity of propylene units in the ethylene–propylene–diene copolymers when the crosslinking system is added to acrylonitrile-butadiene rubber.
