The effect of bromobutyl caoutchouc BBK-232, sevilene 11808-340, divinylstyrene caoutchoucs DSSK-628V and SKMS-30ARK on the rheometric characteristics of the rubber mixture, physical, mechanical, operational and dynamic properties of rubber used for the manufacture of seawater-resistant products are studied. Along with the listed ingredients, the rubber mixture contained a vulcanizing agent - sulfur; vulcanization accelerators - 2,2'-dibenzothiazole disulfide, diphenylguanidine; vulcanization activators - zinc white, stearin; antioxidant - naphtham-2; fillers - technical carbons P 514 and P 803, natural chalk; polymer filler - trans-polynorbornene; softeners - rosin, petroleum polymer resin "Shinplast", factice; plasticizer - petroleum bitumen. It was found that rubber based on DSSK-628V and BBK-232 couutchoucs with their mass ratio of 75:25 not containing sevilen 11808-340 has better rheometric, physical-mechanical, dynamic properties and resistance to sea water.
