    摘要: An elastomeric blend composition having improved tear properties and having a viscosity at 0.73 sec.sup.-1 and at 200.degree. C. of about 8.times.10.sup.3 to about 8.times.10.sup.5 poises, said composition formable into an elastomeric article, which comprises:(a) a neutralized sulfonated EPDM terpolymer having a viscosity at 0.73 sec.sup.-1 and at 200.degree. C. of about 5.times.10.sup.4 poises to about 5.times.10.sup.6 poises and about 10 to about 50 meq. sulfonate groups per 100 grams of said sulfonated EPDM terpolymer, said sulfonate groups being neutralized; and(b) about 2 to about 60 parts by weight of a fluorohydrocarbon elastomer per 100 parts of such sulfonated EPDM terpolymer.
