Title (EN) HYDROPHOBIC VINYLAMINE-CONTAINING POLYMER COMPOSITIONS AND THEIR USE IN PAPERMAKING APPLICATIONS
(FR) COMPOSITIONS POLYMÈRES HYDROPHOBES CONTENANT UNE VINYLAMINE ET LEUR UTILISATION DANS DES APPLICATIONS DE FABRICATION DE PAPIER
Abstract:
(EN) Disclosed herein are hydrophobic vinylamine-containing polymers useful as papermaking performance additives for enhancing paper softness with little or no negative effect on paper dry strength properties. The hydrophobic vinylamine-containing polymers are produced by incorporating hydrophobic functional property into primary amine moiety of the vinylamine-containing polymers via reactions with reactive hydrophobes. The hydrophobically modified vinylamine-containing polymers can be further used as base polymers for polymerization with a vinyl monomer by free radical initiated polymerization. The compositions of those hydrophobic vinylamine-containing polymers have shown improved softness, reduced coefficient friction to paper products while maintained or improved dry strength properties of the paper products.
(FR) L'invention concerne des polymères hydrophobes contenant une vinylamine, servant d'additifs de performance de fabrication de papier destinés à augmenter la douceur du papier avec peu ou pas d'effet négatif sur les propriétés de résistance à sec du papier. Les polymères hydrophobes contenant une vinylamine sont produits par incorporation d'une propriété fonctionnelle hydrophobe dans une fraction amine primaire des polymères contenant une vinylamine par l'intermédiaire de réactions avec des hydrophobes réactifs. Les polymères contenant une vinylamine à modification hydrophobe peuvent en outre s'utiliser comme polymères de base pour une polymérisation avec un monomère vinylique par polymérisation radicalaire. Les compositions de ces polymères hydrophobes contenant une vinylamine ont démontré une douceur améliorée, un frottement à coefficient réduit pour des produits en papier tout en conservant ou en améliorant les propriétés de résistance à sec des produits en papier.
