Title
(EN) STABLE POLYAMIDE RESIN DISPERSIONS AND METHODS FOR THE MANUFACTURE THEREOF
(FR) DISPERSIONS STABLES DE RESINES POLYAMIDES ET PROCEDE DE FABRICATION DESDITES DISPERSIONS
Abstract
(EN)
A stable aqueous dispersion of polyamide resin in water comprising a surfactant and at least one amino acid of formula (I), or an anionic or cationic salt thereof, wherein 'R' represents an alkylene, akenylene or arylene group of one to ten carbon atoms and 'Y' is hydrogen or a polar or non-polar ionic or non-ionic substituent, in an amount effective to improve the stability of said aqueous dispersion.
(FR)
Dispersion aqueuse stable de résines polyamides dans de l'eau comprenant un tensioactif et au moins un acide aminé de la formule (I), ou un sel anionique ou cationique dudit acide, dans laquelle 'R' représente un groupe alkylène, acénylène ou arylène ayant de un à dix atomes de carbone et 'Y' est de l'hydrogène ou un substituant ionique ou non ionique polaire ou non polaire, dans une quantité efficace pour améliorer la stabilité de ladite dispersion aqueuse.
