Abstract

PURPOSE: A rubber composition, prepared by incorporating a halogenated diene polymer having active halogens with a rubber, and having improved elasticity without degrading the processability and tensile strength, and widely usable for rubber.
CONSTITUTION: A rubber composition prepared by incorporating 3W40wt% halogenated diene polymer with a halogen content of 2W15wt% and active halogens obtained by the Wohl-Ziegler reaction or the reaction of a halogen with a diene polymer with 97W60wt% rubber, particularly isoprene rubber, e.g. NR or IR. A diene polymer having a molecular weight ≥100,000 or an intrinsic viscosity ≥1.5 in toluene at 30°C is preferred as the diene rubber from the viewpoint of the improved elasticity. Polybutadiene rubber is particularly suitable.
