    摘要： THERE IS PROVIDED A PROCESS FOR PRODUCING FIRE RETARDANT EPOXY RESINS WHICH COMPRISES CURING A MIXTURE OF (1) AN EPOXY RESIN AND (2) A PHOSPHORAMIDATE OF A FORMULA SELECTED FROM THE GROUP CONSISTING OF:

    (R-O-)X-P(=O)(-NH-R'')Y AND R".(-O-P(=O)(-NHR'')-O-)

    WHEREIN R IS ALKYL, ARYL, SUBSTITUTED ALKYL OR SUBSTITUTED ARYL R'' IS HYDROGEN OR R, R" IS HYDROCARBYLIDENE, X IS O TO 2, Y IS 1 TO 3 AND THE SUM OF X AND Y IS 3. AN AMINE CAN BE EMPLOYED TO IMPROVE THE PROCESS.

    摘要： THE INVENTION INCLUDES NEW CYCLIC PHOSPHOROAMIDATES, NEW COMPOSITIONS THEREOF, AND A NEW PROCESS FOR THE MAKING OF THE NEW CYCLIC PHOSPHOROAMIDATES. A TYPICAL NOVEL CYCLIC PHOSPHOROAMIDATE OF THIS INVENTION IS A COMPOUND OF THE FORMULA:

    2-(HO-CH2)2-N-1,3,2-DIOXAPHOSPHORINAN-2-ONE

    WHICH IS AN EFFECTIVE FIRE RETARDANT FOR VARIOUS COMPOSITIONS SUCH AS POLYURETHANE FOAM, FOR EXAMPLE. A COMPOUND OF THIS ILLUSTRATIVE FORMULA MAY BE PREPARED BY REACTING THE DI-FUNCTIONAL AMINE PRECURSOR THE COMPOUND, WITH FORMALDEHYDE. THE ABOVE ILLUSTRATIVE COM POUND ALSO MAY BE EMPLOYED AS AN INTERMEDIATE IN THE PRODUCTION OF OTHER COMPOUNDS AND/OR COMPOSITIONS DESCRIBED IN THE SPECIFICATION.
