Abstract
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.
