FREE RADICALLY POLYMERIZABLE SILOXANES AND SILOXANE POLYMERS

Free radically polymerizable synthons for preparing siloxane polyoxamide copolymers are prepared by reacting amine-terminated siloxane polyoxamide compounds with an isocyanate-functional (meth)acrylate, an isocyanate-functional vinyl-substituted aromatic compound, or a vinyl azlactone. These free radically polymerizable synthons can be used to prepare polymer compositions by combining the free radically polymerizable synthons with an initiator and initiating polymerization.
