Abstract: of the disclosure: Polyol/epoxy adducts for use as emulsifier for liquid epoxy resins Polyol/epoxy adducts obtained by reaction of (A) an aliphatic polyol having an average molecular weight (Mw) of 200 to 20000 and (B) an epoxy compound having at least two epoxy groups per molecule and an epoxy equivalent weight of 100 to 2000, the equivalent ratio of the OH groups to the EP groups being 1:3.51 to 1:10, preferably 1:4 to 1:9, particularly preferably 1:4.5 to 1:8, and the epoxy equivalent weight of the adduct being between 150 g/eq and at least 8000 g/eq, preferably between 250 g/eq and 1000 g/eq. These adducts serve as nonionic emulsifier in waterdilutable epoxy liquid resins.

Abstract: -1 - HOE 91/F 050 : A process for the preparation of perfluoropolyetheracyl fluorides. A process for the preparation of perfluoropolyetheracyl fluorides of formula (I) F3C(CF2)2-O-¢CF(CF3)CF2-O-!nCF(CF3)COF (I) in which n is an integer from 0 - 60, wherein hexafluoropropylene oxide is oligomerized in the presence of CsF and a polyethylene glycol dimethyl ether and the reaction mixture thus formed is reacted with at least one of the halogen compounds HCl, HBr, BCl3, PCl3, SCl2 and RmSiCl4m, where m = 0, 1, 2 or 3 and R = C1-C3-alkyl or phenyl, dissolved in an aprotic colvent.
