Abstract
A process for preparing carboxylates of polyoxyalkylene siloxanes and -amines, alkylpolyoxyalkylenes, polyoxyalkylene block polymers, alkylamidepolyoxyalkylenes and alkylpolyglucosides comprising subjecting a primary hydroxyl group-containing polyoxyalkylene compound or alkylpolyglucoside to mild oxidiation. The invention also relates to the novel polyoxyalkylene amine and alkylamidepolyoxyalkylene carboxylates prepared by the process.
Claims32
A process for preparing a polyoxyalkylene siloxane carboxylate comprising reacting a primary hydroxyl group-containing polyoxyalkylene siloxane with at least an equimolar amount of either an inorganic or organic halo-containing oxidizing agent in the presence of a weak base and a catalytic amount of a hindered nitroxide.
