CA 2212814

The use of enol ether capped polyether-polysiloxane copolymers as surfactants in polyurethane foam applications is taught herein. These enol ether capped surfactants exhibit a high capping efficiency and yield good performance. Moreover, they are stable in water/amine premixes.

Utilisation de copolymères polyéther-polysiloxane à extrémité protégée par un éther énolique, en tant que tensioactifs dans les applications mettant en oeuvre la mousse polyuréthane. Ces tensioactifs à extrémité protégée par un éther énolique présentent une efficacité de protection élevée et un bon rendement. Par ailleurs, ils sont stables dans les prémélanges du type eau/amine.
