    Abstract: of the disclosure: 2,5-Dioxo-1,2-oxa-phospholanes of the formula (I) (I) wherein R1 is an organic radical and R2 and R3 each also means organic radicals or hydrogen, are prepared by reacting 2-halogeno-formylethyl-phosphinic acid halides of the formula (II) (II) wherein R1, R2 and R3 are defined as in formula (I) and X means Cl or Br, preferably Cl, with an approximately equimolar quantity of acrylic acid. The compounds (II) may also be produced in the reaction batch and in situ by reacting about equimolar quantities of a dihalogenophosphine of the formula (III) (III) with an .alpha.,.beta.-unsaturated acid (IV) CHR2=CR3-COOH (IV) In the formulae (III) and (IV) R1, R2, R3 and X are defined as indicated above. In the reaction there is formed, in addition to the compounds (I), practically exclusively .beta.-halogenopropionic acid and no free hydrogen halide. The phospholanes (I) are valuable flame retarding agents for plastics, intermediates, for example, for the synthesis of biocidals etc. - 1a

    Abstract: A curing agent (A) for resins (B) which can be cured by means of isocyanates, which has an amine number of 20 to 150 mg of KOH/g and an OH number of not more than 20 mg of KOH/g and which contains per molecule at least two masked isocyanate groups which are reactive under the conditions of curing, obtained by reacting (a) an amine which contains at least one .beta.-hydroxyalkyl group per molecule and has an OH number of 100 to 1,200 mg of KOH/g and an amine number of 100 to 1,200 mg of KOH/g and which, if appropriate, also contains NHCO groups, if appropriate as a mixture with another OH-functional and/or NH-functional compound, with (b) a partly masked isocyanate, if appropriate as a mixture with an at least difunctional, OH-reactive and/or NH-reactive compound. These curing agents are readily dispersible in aqueous systems, if appropriate after neutralization, and frequently increase stability in aqueous paint formulations.
