Abstract

Abstract Translated from French Polyesters sulfonés greffés constitués d'un tronc de polyester sulfoné portant des greffons dérivés d'une composition monomère à base d'acide carboxylique insaturé, d'acrylate de butyle et d'une quantité importante d'ester monoéthyléniquement insaturé d'un acide carboxylique (acétate de vinyle). Grafted sulfonated polyesters consisting of a sulfonated polyester trunk carrying grafts derived from a monomer composition based on unsaturated carboxylic acid, butyl acrylate and a large amount of monoethylenically unsaturated ester of a carboxylic acid ( vinyl acetate). Ils sont préparés par polymérisation de la composition monomère en présence d'un polyester sulfoné hydrodispersable. They are prepared by polymerization of the monomer composition in the presence of a water-dispersible sulfonated polyester. Les dispersions aqueuses ou les solutions aqueuses desdits polyesters sulfonés greffés peuvent être utilisées pour encoller les fils et les fibres textiles. The aqueous dispersions or the aqueous solutions of said grafted sulfonated polyesters can be used for sizing yarns and textile fibers.
