FIELD: chemistry.
SUBSTANCE: invention relates to a vulcanising polymer composition, a polymer vulcanisate obtained from the polymer composition and a method for production thereof. The vulcanising polymer composition contains (i) a hydrogenated polymer having a polymer backbone chain formed from (ia) 25-89.5 wt %, preferably 30-80 wt % and more preferably 45-75 wt % with respect to the polymer of a first monomer, which includes at least one secondary carbon atom and a tertiary carbon atom into the polymer backbone chain, such as at least one diene monomer, and (ib) 10-74.9 wt %, preferably 10-60 wt %, more preferably 15-55 wt %, even more preferably 20-50 wt % with respect to the polymer of a second monomer, such as an α,β-ethylenically unsaturated nitrile monomer; (ic) 0.1-20 wt %, preferably 0.5-20 wt %, more preferably 1-15 wt %, even more preferably 1.5-10 wt % with respect to the polymer of at least one monomer of a monoester of α,β-ethylenically unsaturated dicarboxylic acid, a monomer of α,β-ethylenically unsaturated dicarboxylic acid, a monomer of an anhydride of α,β-ethylenically unsaturated dicarboxylic acid or a diester of α,β-ethylenically unsaturated dicarboxylic acid as a third monomer, where the total content of all monomer links given in (ia), (ib) and (ic), is equal to 100 wt %; (ii) at least one cross-linking agent - polyamine, and (iii) at least one bi- or polycyclic amine-base which is selected from a group comprising 1,5-diazabicyclo[4,3,0]-5-nonene (DBN), 1,4-diazabicyclo[2.2.2]octane (DABCO) 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBC), 7-methyl-1,5,7-triazabicyclo[4.4.0]dec-5-ene (MTBD) and derivatives thereof. The invention also relates to a polymer vulcanisate and a method for production thereof.
EFFECT: obtained vulcanisates demonstrate high cross-link density and have improved properties.
