    摘要: Liquid bromine-containing alkoxylation products of butyne-(1,4)-diol which are storage stable are produced. More specifically, 1.5 to 2.5 mols alkylene oxide are reacted with each mol of butyne-(1,4)-diol present at elevated temperature in the presence of a catalyst. The catalyst is selected from (1) thioethers having a molecular weight of up to 5000 obtained by adding a mercaptan and/or mercaptoalcohol to an unsaturated hydrocarbon and/or (2) thioethers other than those of (1) having a molecular weight of from 500 to 5000 and/or (3) alkali metal chlorides. This alkoxylation product is then reacted with bromine at -10.degree. to 80.degree. C. The bromide is reoxidized with aqueous hydrogen peroxide solution, stabilized with a relatively non-volatile epoxide and dehydrated. The product thus obtained is particularly useful in the production of flame resistant isocyanate addition products such as polyurethane foams.

    摘要: Oligoesters having hydroxyl groups and an OH number of from 200 to 600 mg KOH/g are made by reacting a cyclic dicarboxylic acid anhydride in which no halogen is present with a polyfunctional alcohol or dialkanolamine in a molar ratio of from 1:0.5 to 1:1.5 at a temperature of from 50.degree. to 150.degree. C. to form the corresponding dicarboxylic acid semiester and/or semiamide. This semiester and/or semiamide is then alkoxylated with ethylene oxide and/or propylene oxide in the presence of a catalyst at 80.degree. to 150.degree. C. The equivalent ratio of acid groups to alkylene oxide groups is from 1:0.8 to 1:1.7. The catalysts are reaction products of alkoxides with at least 3 C-atoms with ammonia, piperidine, piperazine and/or C.sub.2 -C.sub.6 aliphatic, polyamines, preferably diamines in which all of the NH-functional groups have been alkoxylated. The resultant oligoester may then be reacted with a polyisocyanate optionally in the presence of known additives, such as blowing agents and catalysts.
