Abstract: Nitrones are produced by reaction of primary amine with aldehyde or ketone, in the presence of a transition metal-containing oxidation catalyst, and a peroxidic compound. The nitrone can then be reacted with a vinylaromatic compound to produce a 2-hydrocarbyl-5-arylisoxazolidine.

Abstract: Polyether organic compounds are described which have both imine and hydroxyl functionality. These materials are synthesized by reacting a primary amine with an aldehyde or ketone to form a Schiff base. By definition, a Schiff base comprises the reaction product of a primary amine and an aldehyde. In this case, however, unlike conventional Schiff bases, the reaction product possesses both hydroxyl and Schiff base functionality. In one embodiment of the invention, such a product is produced by the reaction of a polyoxyalkyleneamine (Jeffamine) with p-nitrobenzaldehyde and glycidol. The result is a polyether having both hydroxyl and Schiff base functionality. The compounds produced in this manner are particularly useful as bonding agents in the formulation of solid propellants. The bonding agents provide superior performance, while avoiding the problems encountered when using existing bonding agents.
