Модификация этилен-пропилен-диеновых эластомеров с помощью добавления фрагментов ускоряющих агентов для улучшения их совместимости с бутадиен-нитрильными каучуками и снижения скорости деструкции под действием озона полидиеновой матрицы является эффективной только в случае низкой стереорегулярности пропиленовых звеньев в этилен-пропилен-диеновых сополимерах. Если изотактичность фрагментов пропилена в цепи этилен-пропилен-диеновых эластомеров высока, то их модификация приводит к уменьшению стойкости сшитой смеси к действию озона.

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 isotacticity of propylene fragments in the chains of ethylene-propylene-diene elastomers is high, their modification leads to a reduction in the ozone resistance of the crosslinked blend.
