NR or SBR latex mixed with acrylonitrile by the procedure (i) mentioned in the previous paper was irradiated with gamma-rays yielding rubbers with different grafting ratios. On the other hand, blended polymers, of which the acrylonitrile contents were made equal to the grafted polymers respectively, were produced by blending NBR with NR or SBR. Comparison of physical properties of compounded stocks and vulcanizates of grafted polymers with those of the corresponding blended polymers gave similar results to those reported in the previous paper.
