    Abstract: Elastic epoxy resin composition including (A) compounds having at least two 1,2-epoxide groups, which are obtainable by reaction of polyepoxides (A1) having at least two epoxide groups per molecule and polyoxyalkylene monoamines (A2) and optionally polycarboxylic acids (A3), (B) optionally compounds having at least two 1,2-epoxide groups, which are obtainable by reaction of polyepoxides (B1) having at least two 1,2-epoxide groups per molecule and sterically hindered aliphatic monoamines (B2), (C) 1,2-epoxide compounds which are chosen from polyepoxides which differ from (A1) and (B1) and the unreacted contents of the compounds (A1) or (B1) from the preparation of the compounds (A) and (B), (D) .omega.-imi-dazolyl-alkanoguanamines, (E) latent curing agents and (F) if appropriate further additives, are useful, for example, in elastic coatings and elastic adhesives.

    Abstract: 92/K 009 of the disclosure: Hardeners for epoxy resins, comprising reaction products of (A) polyamidoamines that were obtained by polycondens ation of (a) dicarboxylic acids containing oxyalkylene groups, or their derivatives, with (b) polyamines containing at least two amino groups capable of undergoing condensation with (a), (B) polyamines containing at least two secondary amino groups, and (C) adducts of (c) polyepoxy compounds and (d) poly alkylene polyether polyols. Epoxy resins that have been cured with these hardeners exhibit in particular a very good water resistance.

    Abstract: 1. A process for the preparation of 2-oxo-1,3-dioxolanes by reaction of epoxides with carbon dioxide in the presence of a catalyst and, if necessary, an inert solvent, wherein the reaction is effected at temperatures from 40 to 180 degrees C and at normal pressure or slightly increased pressure in the presence of at least one catalyst from the group comprising triphenylphosphane, tritolylphosphane, diazabicyclo[2.2.2]octane, 4-dimethylaminopyridine, 4-(1-pyrrolidinyl)pyridine, amidines, imidazole and the alkyl, aryl, or aralkyl substitution products thereof.
