FIELD: polymers.
SUBSTANCE: ethylenepropylene copolymer-base composition comprises dicumyl peroxide, bis-(tert.-butylperoxyisopropyl)benzene or 1,1-di-tert.-butylperoxy-3,3,5-trimethylcyclohexane as an organic peroxide and vinyltri-(methoxyethoxy)silane or polyphenylethoxysiloxane as an organosilicon additive. Except for, the composition comprises additionally a vulcanization co-agent taken among the group including low-molecular polybutadiene with the content of 1,2-links 20-80%, trimethylolpropane-trimethacrylate, triallyl cyanurate and quinone dioxime-1,4. Also, the composition comprises stearin, paraffin and zinc oxide. The composition shows high physical-mechanical properties, oil-resistance and dielectric properties. Invention can be used, in particular, in cable industry.
EFFECT: valuable properties of composition.
