Claim 1
Independent Claim
148 words
THE METHOD OF VULCANIZING ETHYLENE-PROPYLENE TERPOLYMERS, THE THIRD COMPONENT OF WHICH IS AT LEAST ONE MULIIPLE OLEFINICALLY UNSATURATED COMPOUND HAVING 4 TO 14 CARBON ATOMS, WITH A PHENOL ALDEHYDE RESIN WHICH COMPRISES VULCANIZING AN ELASTOMER COMPOSITION OF SAID ETHYLENE-PROPYLENE TERPOLYMER, A PHENOL ALDEHYDE RESIN, A FILLER AND A COMPLEX COMPOUND OF THE GENERAL FORMULA XMME(R1OR2)N, WHEREIN, IN THE SAID FORMULA, X IS A HALOGEN, ME IS A HEAVY METAL OF A SPECIFIC GRAVITY GREATER THAN 4, M AND N ARE INTEGERS FROM 1 TO 4 EACH AND R1, AND R2 ARE RADICALS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND RADICALS HAVING FROM 1 TO 14 CARBON ATOMS BEING MONOVALENT HYDROBAECON RADICALS, MONOVALENT HYDROCARBON RADICALS INTERRUPTED BY AN ETHER OXYGEN ATOM, AND BIVALENT DERIVATIVES OF THAT RADICAL IN WHICH THE TWO VALENCES ARE BOUND TO R1 AND R2 SO AS TO FORM A RING WITH THE GROUP R1OR2.
