  • Patent number: 4939251
    Abstract: Novel 1-azaspiro[4.4] lactams are produced by reaction of at least one hydroxy-containing primary amino compound with a 4-ketodiacid compound or a 1,6-dioxaspiro[4.4]lactone. Molar excesses of amion compound result in production of spirodilactams, while limited molar quantities of amino compound results in production of a spirolactam-lactone which reacts further with hydroxy-containing primary amino compound or with hydroxy-free primary amino compound to produce a spirodilactam. Certain of the spirolactams are useful as precursors for glycidyloxy derivatives which react with epoxy curing agents to form insoluble thermoset resins while others are useful as curing agents and yet others are converted to glycidyloxy derivatives useful as reactive diluents in epoxy resin applications.
