CA 2288329

The reactions of cyclic carbonates, especially 1,3-dioxolan-2-ones, with amines, especially primary amines, are catalyzed by the presence of a base whose conjugate acid has a pKa of about 11 or more. The products are hydroxy urethanes, and the process can be used to form cross-linked polymers which contain urethane groups. Such cross-linked polymers are useful in coatings.

Selon l'invention, les réactions de carbonates cycliques, en particulier des 1,3-dioxolan-2-ones, avec des amines, en particulier des amines primaires, sont catalysées par la présence d'une base dont l'acide conjugué présente un pKa d'au moins environ 11. Les produits obtenus sont des hydroxy-uréthanes, et le procédé peut être utilisé pour former des polymères réticulés qui contiennent des groupes uréthane. De tels polymères réticulés peuvent être utilisés dans des revêtements.
