CA 1111189

Abstract of the Disclosure Shaped objects including synthetic polymeric fibers with improved antistatic properties are prepared by incorporation therein about 1 to about 15% of a polyester antistatic agent prepared by reacting an N,N-bis(hydroxyalkyl) taurine salt with an organic polycarboxylic acid. Incorporation of the polyester into a synthetic polymer is accomplished by the process of preparing a melt or solution of the synthetic polymer and the polyester and extruding from the melt or casting from the solution to provide films, fibers and other molded objects exhibiting antistatic properties. A process for the preparation of the polyester antistatic agents of the invention, and for the preparation of the N,N-bis(hydroxyalkyl) taurine salts is also disclosed. -1-
