초록

Bonding agents for use in formulating solid propellants are described. The bonding agents have a Schiff base, or Schiff base and hydroxyl or amine functionality. These materials are synthesized by reacting a primary amine with an aldehyde to form a Schiff base. By definition, a Schiff base comprises the reaction product of a primary amine and an aldehyde. 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 hydroxy...
