    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.

    Abstract: Epoxy resin compositions (ERC), consisting of (A) compounds with at least two 1,2-epoxide groups, comprising epoxide-amine adducts obtained by reacting (A1) compounds with at least two epoxide groups on average, optionally mixed with mono-epoxides, (A2) amine(s) selected from (A21) sterically hindered mono-amines of formula R -C(R )(NH2)-R -NH-R -NH-R (II) and (A23) di-prim. diamines of formula H2N-C(R )(R )-R -C(R )(R )-NH2 (III); and (A3) polyfunctional aromatic, linear, branched or cyclic aliphatic, or aromatic-aliphatic isocyanates with at least 2 isocyanate groups; (B) optionally 1,2-epoxide compounds other than (A1), and/or the unreacted residues of (A1) from the production of (A); (C) hardeners and (D) optionally other additives. In (I)-(III), R = 1-30C (cyclo)aliphatic, araliphatic or aromatic hydrocarbyl, optionally substituted with OH, alkoxy or halogen; R , R = H or R , preferred R is H; the amino groups in (I) are not directly attached to an aromatic ring; if R = R = H, then R = -CHR R (7), -CR R R (8), -CH2-CHR R (9) or -CH2-CR R R (10), with R -R = as for R ; R may also form an optionally substituted cycloaliphatic ring with up to 8C atoms, in which case R = H; R = optionally substituted hydrocarbyl (as for R ) with 2-30C, or (poly)oxyalkylene with 1-200 units; R = optionally substituted hydrocarbyl as for R with 1-20C; at least one carbon directly attached to nitrogen in formula (II) is a sec. or tert. carbon; R -R = H or 1-8C alkyl; R = direct bond, optionally substituted alkylene, or arylene or heteroarylene; at least one of the groups R -R is alkyl if R is a direct bond or linear alkylene, and R can form a cycloaliphatic, aromatic or heteroaromatic ring with R or R and the linking atoms.

    Abstract: Epoxide-amine adducts (I) are claimed, contg. at least 20 wt% aliphatic epoxide and/or amine units with at least one tert. or quat. carbon atom. Also claimed are: (i) binders for coatings, contg. adduct(s) (I); (ii) mixts. of 0.1-99.9 wt% OH gp.-contg. copolymers and 99.9-0.1 wt% (I); (iii) binders for coatings, contg. mixts. (ii); (iv) coating materials contg. these binders, together with hardeners such as amino resins, capped or uncapped polyisocyanates and cpds. with acid and/or anhydride gps.. Pref. (I) are obtd.: (A) by reacting (a) 7-33C (cyclo)aliphatic mono-epoxides (a1), at least 20 wt% of which comprises monoepoxides with a tert. or quat. C atom with (b) 2-30C amines with at least 2 prim. or sec. amino gps. not attached directly to an aromatic ring; or (B) by reacting (a) 8-50C (cyclo)aliphatic diepoxides (a2) with (b) 4-30C prim. or sec. mono-amines with amino gps. not directly attached to aromatic rings, of which at least 20 wt% comprises mono-amines with at least one tert. or quat. C atom; or (C) by reacting (a1) with (b), the corresp. proportions of mono-amine and mono-epoxide with tert. or quat. C atoms being a% and b% respectively, where a + b = 20 and both a and b are greater than zero. The functionality of (I) is reduced by partial or complete reaction of the functional OH and amino gps., pref. by blocking with temporary protecting gps., esp. oxazolidine gps..
