Abstract
Novel siloxane compounds having N-alkylpyrrolidone incorporated therein as well as a reactive group such as amino, epoxy, acryl, methacryl, carboxyl, mercapt or carbinol group in their molecule possess the characteristics of both silicone and pyrrolidone and are highly water soluble. They are prepared by polymerizing an oligomer resulting from hydrolysis of a pyrrolidone-containing silicone, a cyclic siloxane, and a siloxane or by addition reacting an N-allylpyrrolidone to an organohydrogensiloxane. They are useful as fiber treating agents and cosmetic additives, and also effective for modifying various resins.
