Abstract:
Dihydrooxadiazinones are provided which can be used as blowing agents in various thermoplastic polymeric materials to produce high performance thermoplastic foams. A ketone having at least one alpha -hydrogen atom is halogenated and hydroxylated to produce an alpha -hydroxyketone. Condensation of the alpha -hydroxyketone with an organocarbazate produces the corresponding carboorganooxyhydrazone which is cyclized to a dihydrooxadiazinone.
