Modified cis-1,4-polyisoprene rubber obtained by incorporating into cis-1,4-polyisoprene rubber a side chain formed by succinimide residue containing in the N position a hydrocarbon residue having at least one tertiary nitrogen atom. This rubber is excellent in green strength at ordinary room temperature, and flowability at an elevated temperature. Its vulcanizate is comparable to, or better than natural rubber in breaking strength and hardness.
