Amine functional polymers are prepared by polymerization of vinylamides with vinyl ester monomers. The resultant polymers are hydrolyzed under acid conditions and subsequently at least partially basified to the free-base amine. Byproduct salts are removed by precipitation or by extraction into an immiscible phase. The polymers made by this method are crosslinkable through reaction of the amine groups and are useful in high performance coatings, adhesives, binders and the like.

Polymères aminés préparés par polymérisation de vinylamides avec des monomères d'ester vinylique. Les polymères résultants sont hydrolysés dans des conditions acides, puis alcalinisés au moins partiellement en amines, bases libres. Les sels, produits secondaires, sont éliminés par précipitation ou par extraction dans une phase non miscible. Les polymères obtenus par cette méthode sont réticulables par réaction des groupes amines et sont utiles dans des revêtements, des adhésifs, des liants et autres composantes haute performance.
