Description
Summary:	The modification of ethylene-propylene-diene elastomers via the addition of fragments of an accelerating agent or chlorine atoms to improve their compatibility with butadiene-nitrile 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 butadiene-nitrile rubber. 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 independently of the mode of introduction of the crosslinking system.
