Abstract
There are disclosed a resin-reinforced elastomer which comprises as principal components, a rubber and a polyolefin having an average particle diameter of at most 1 .mu.m, and in which the rubber and the polyolefin are linked together; a process for producing the resin-reinforced elastomer by melt kneading a polyolefin, a No.1 rubber and a binding agent to prepare a thermoplastic composition, adding a No.2 rubber to the resultant thermoplastic composition and melt kneading the mixture thus formed to disperse the polyolefin in the rubber components; and a pneumatic tire using the resin-reinforced elastomer in its tread. The above resin-reinforced elastomer has a uniform modulus and a low density, is minimized in directionality, and is excellent in tensile strength, fatigue resistance and abrasion resistance.
