Abstract
PURPOSE: A rubber composition useful for the preparation of a rubber having little temperature-dependent physical properties, high hardness, high modulus and low hysteresis loss, obtd. by the addition of surfur to a raw material rubber contg. a propylene-butadiene alternating copolymer.
CONSTITUTION: A rubber composition comprising at least 2.5pts.wt. sulfur and 100pts.wt. raw material rubber contg. 25pts.wt. or more propylene-butadiene altenating copolymer rubber. The propylene-butadiene alternating copolymer rubber to be used is the one of Mooney viscosity 30W90, in which 90% or more butadiene units are of 1,4-structure. It is impossible to give sufficient hardness by using less than 25pts.wt. said copolymer rubber. The rubber composition is utilized as raw material for rubber material used near the bead portion of a tire and a rubber material used for an industrial appliance which requires high hardness.
