Compositions and textile sizes based on those compositions, which are particular poly(vinyl alcohol) copolymer ionomers, as well as blends of those ionomers with other sizing polymers are described. A process to prepare the ionomers is described. The compositions are poly(vinyl alcohol) copolymers which have carboxylic acid ionomer comonomer units. Sizes based on these ionomers are aqueous solutions of the ionomers or solutions of blends of them with other poly(vinyl alcohol) polymers which are not ionomeric, or solution/suspensions of the ionomers with various starches, or both. Desizing in either water or caustic solutions is generally far superior to comparable polymer blends which contain no poly(vinyl alcohol) copolymer ionomer.

L'invention concerne des compositions et des ensimages textiles basés sur ces compositions constituées d'ionomères de copolymères spécifiques de poly(vinyle alcool), ainsi que des mélanges de ces ionomères avec d'autres polymères d'ensimage. L'invention concerne notamment un procédé de préparation de ces ionomères. Les compositions sont des copolymères de poly(alcool de vinyle) possédant des unités de comonomères d'ionomères d'acide carboxylique. Les ensimages basés sur ces ionomères sont des solutions aqueuses d'ionomères ou des solutions de leurs mélanges avec d'autres polymères de poly(vinyle alcool) non ionomères, ou bien des solutions/suspensions d'ionomères comprenant divers amidons, ou les deux. Le désencollage intervenant dans l'eau ou dans des solutions caustiques est généralement bien supérieur à celui obtenu avec des mélanges polymères dépourvus d'ionomères de copolymères de poly(alcool de vinyle).
