    摘要： A process for flameproofing polyurethanes, particularly polyurethane foams, is provided. It consists in adding a reaction product from dimethyl methanephosphonate, an aliphatic diol or triol and a lower epoxide to the polyurethane components. These reaction products are non-uniform mixtures of different esters of methane phosphonic acid.

    摘要： Stable formulations of fluorescent whitening agents are described. These contain a) 2 to 20% by weight of a fluorescent whitening agent of formula (1) in which R1 is hydrogen, C1-C5-alkyl, C1-C5-alkoxy or halogen and M is hydrogen, an alkali metal, ammonium or magnesium, b) 4 to 30% by weight of an unmodified or modified polyvinyl alcohol, c) 55 to 94% by weight of water and d) 0 to 20% weight of further additives, polyethylene glycol being excluded. A process for the preparation of the formulations and their use for whitening paper materials is also described.
