Title
(EN) MODIFIED EPOXIES FOR PAPER SIZING
(FR) RESINES EPOXYDES MODIFIEES POUR COLLAGE DU PAPIER
Abstract
(EN)
Hydrophobically modified epoxy resin comprising (a) a polyfunctional epoxy resin backbone optionally chain extended with at least one difunctional group and (b) at least one hydrophobic moiety, such resin being particularly well suited as sizing agent for paper.
(FR)
L'invention concerne une résine époxyde rendue hydrophobe comportant (a) un squelette de résine époxyde polyfonctionnel à chaîne éventuellement allongée par au moins un groupe difonctionnel, et (b) au moins une fraction hydrophobe, cette résine convenant particulièrement bien comme agent de collage pour papier.
