POLYMER COMPOSITION Russian patent published in 2018 - IPC C08L23/22 C08L23/16 C08K13/02 

FIELD: chemistry.

SUBSTANCE: invention relates to a polymer composition, intended for the manufacture of rubber products operated at extreme temperatures and high pressures. Composition comprises a mixture of rubbers, which are ethylene-propylene rubber and butyl rubber, selected from the group consisting of butyl rubber chlorobutyl rubber and bromobutyl rubber. In addition, the composition contains stearic acid as a vulcanization retarder, of Hexol CXP as a multifunctional modifier, white zinc as an activator, technical carbon №330 as a filler, a curing agent, which is an alkyl phenol resin "Ribetak" and Aerosil A-300 hydrophilic with the functions of stabilizer and antiseptic additive of multicomponent systems.

EFFECT: obtained polymer composition has a high complex of physical and mechanical parameters, allowing to increase the strength, stability and useful life of the products obtained.
