Abstract
A novel rubber compound which comprises 100 parts by weight of a rubber component (I), 0.1-15 parts by weight of an amine salt of carboxylic acid (II) and 0-7 parts by weight of sulfur (III), said rubber component (I) consisting of 40-100% by weight of an elastomeric copolymer (A) and 60-0% by weight of a vulcanizable rubber (B); said elastomeric copolymer (A) being composed of a C.sub.4 or C.sub.5 conjugated diene, styrene, and a glycidyl group-containing monomer; the amount of said conjugated diene, the total amount of said conjugated diene and said styrene and the amount of said glycidyl group-containing monomer being 50% by weight or more, 80-99.5% weight and 0.5-20% by weight, respectively, based on the weight of said elastomeric copolymer (A); and the content of said glycidyl group-containing monomer in said rubber component (I) being 0.5% by weight or more, does not undergo scorching at the time of processing and gives, when vulcanized (crosslinked), a vulcanized rubber having a high modulus of elasticity.
