Abstract: The antistatic properties of hydrophobic synthetic fibers are improved by treatment with an aqueous mixture containing at least one copolymer prepared by copolymerization of a mixture of (I) monoester selected from alkoxy-polyalkyleneglycol-acrylates or alkoxy-polyalkylene-glycol-methacrylates and (II) diester selected from diacrylates and dimethacrylates of polyols. An improvement in the treatment is made by addition of (III) acrylonitrile or vinyl esters of alkyl-alcohols with more than 8 carbon atoms to the copolymerization mixture in order to increase the durability of the antistatic properties of the fibers as a result of laundering and dry cleaning, and to improve the handling qualities.
