    摘要： The invention relates to s-triazine radical-containing polyether polyol mixtures having functionalities of from 2 to 6 and hydroxyl numbers of from 210 to 640, prepared by the oxyalkylation of a mixture of one or more polyamino-1,3,5-triazines, preferably melamine, and an alkanol having a hydroxyl functionality of from 2 to 6 and having 2 to 18 carbon atoms, water, or their mixtures, in the absence of catalysts and conventional inert polar solvents. The resulting polyether polyol mixtures are suitable for the preparation of rigid polyurethane, polyisocyanurate, and urethane group-containing polyisocyanuate foams produced by means of the polyisocyanate polyaddition process.

    摘要： A process for the preparation of polyester polyols having an acid number of less than 1, a hydroxyl number of approximately 20 to about 400, and having a functionality of efficaciously 2 to 3, wherein polycarboxylic acids and/or their anhydrides and multivalent alcohols are polycondensed, preferably in the absence of common esterification catalysts, at temperatures of from about 150.degree. to 250.degree. C., optionally under reduced pressure, up to an acid number of from 20 to 5. The resulting polycondensate is then oxyalkylated per carboxyl group using from 1 to 5 moles of an alkylene oxide, for example 1,2-propylene oxide and/or preferably ethylene oxide, in the presence of at least one tertiary amine catalyst from the group consisting of N-methylimidazole, diazabicyclo[2,2,2]octane, diazabicyclo[5,4,0]undec-7-ene and pentamethyldiethylenetriamine and mixtures thereof, in a quantity of from about 0.001 to 1.0 weight percent based on the weight of the polycondensate, at temperatures from about 100.degree. to 170.degree. C. and under a pressure of about 1 to 10 bar.
