Patent

CA 2650870

The compositions of the present invention comprise silicone copolymers, terpolymers and higher order polymers that comprise 1) polyether substituted structural units and 2) epoxy or oxirane structural units that are reacted with acrylate species to produce cross linked silicones comprising polyether substituted structural units and acrylate cross links. The cross linked polymers of the present invention are self- emulsifying and may be either water swellable or oil swellable.

L'invention concerne des compositions qui comprennent des copolymères, des terpolymères et des polymères d'ordre supérieur de silicone qui comportent : 1) des unités structurales à substitution polyéther; et 2) des unités structurales époxy ou oxirane ayant réagi avec des espèces acrylate afin d'obtenir des silicones réticulés contenant des unités structurales à substitution polyéther et des réticulations acrylate. Les polymères réticulés de l'invention sont auto-émulsifiants et peuvent être gonflés par de l'eau ou de l'huile.
