Abstract

PURPOSE: An oil absorbent that contains specified amounts of an acrylonitrile polymer or copolymer, a thermoplastic elastomer containing conjugate diolefin and a surface active agent, thus showing excellent oil-absorbing ability even when oil is dispersed or emulsified in water.
CONSTITUTION: At least (A) 10wt% of acrylonitrile polymer or copolymer and (B) 30wt% of a thermoplastic elastomer containing a conjugate diolefin and vinyl-substituted aromatic compound (preferably by 10W70%) where the molecular weight of the block copolymer is preferably 5,000W500,000 are mechanically mixed. Then, the resultant mixture is dipped in a 0.05% solution of a surfactant such as a cation surfactant of high molecular weight and heat treated to give the objective oil absorbent.
EFFECT: It removes oily sustances dispersing in water.
USE: It is used in waste water to recover cutting and rolling oil.
