PURPOSE: Provided is a novel polybutadiene derivative, which can eliminates odors from the industrial area and the surroundings by reacting with odor material, especially, which can eliminate toxic material exhausted to the atmosphere from the industrial area. CONSTITUTION: The polybutadiene derivative (formula I) with a molecular weight of 1000-6000 is produced by a process comprising the steps of: reacting hydroxy-substituted polybutadiene and alkyl amine; reacting the resultant with sulfuric acid; reacting the resultant with alkyl amine to alkylate the amine group of the polybutadiene additionally; neutralizing the obtained compound with hydroxide of an alkali metal or an alkali earth metal to convert a sulfonic acid group into a metal salt. In the formula, n is an integer, R1 and R2 are C1-C5 alkyl, and M is the alkali metal or the alkali earth metal.
