PROPERTIES OF VULCANIZATES OF ETHYLENE-PROPYLENE-DIENE TERPOLYMER OBTAINED AT HIGH TEMPERATURES
The properties of the vulcanizates of ethylene-propylene-diene terpolymer of two types (including oil-extended) obtained at 190 °C by using of sulfur and phenolic resin vulcanizing systems were investigated. The analysis of sol fraction of vulcanizates was carried out, their values of the crosslink densities and mechanical characteristics were determined. It was shown that presence of oil leads to a more uniform distribution of crosslinks by volume. The character of deformation and mechanical properties determine by terpolymer nature and type of vulcanizing system.
