    Abstract: Amino-urethanes (I) claimed are of formula R3-N(Re)-A-R1-NH-C(O)-O-CH2-CH(OH)-CH2- R-CH2-CH(OH)-CH2-O-C(O)-NH- R1-A-N(R2)R3 R is residue of a diglycidyl ether or ester, or 2-18 alkylene gp.; R1 is opt. branched 2-18C alkylene; R2 is H, 1-8Calkyl, or 1-8C hydroxyalkyl; R3 is R2, or R3 with R2 can form cyclic ring, or, if R2 is H then R3 can be at least one gp. of formula (a) -C(O)-O-CH2-CH(R4)-CH2- (R-CH2-CH(R4)-CH2-OmB-(R4)n R4 is OH or -CONH-PI-NHCO R6; B is residue of a polyol; m is 1-3; n is 1-6; and PI is residue of a polyisocyanate and R6 is residue of (cylco)aliphatic, or alkylaromatic alcohol, an aminoalcohol, ketoxime, or a CH- or NH- acidic cpd.: b) R3 is gp. of formula (I) R5 is H or R4; R7 is 1-8Calkyl; and s is 1-6; c) -C(O)-NH-PI-NH-C(O)-O-B-d)R8-CHOH-CH2-O-CO-; e) R8-CHOH-CH2-; R8 is H, 1-18C alkyl, or residue of a glycidyl ester or ether; or f) PI'NHCO- PI' is residue of a partly capped polyisocyanate; and A 75 chemical bond or -R1NH)r-R1NH- r is 0-6. Prodn. of a (I) by heating an at least bifunctional 2-oxo-1,3-dioxolan (II) and a prim polyamine at 20-150 deg.C is claimed. Structural formulae are given for pref. R, viz. residues of a bisphenol diglycidyl ether opt. linked by residues of a diamine, diol, dicarboxylic acid, di-isocyanate, etc. Pref. (II) is bicyclic carbonate of specified formuls esp. derived from polyglycidyl ether of a polyphenol, or a epoxide-cyclic carbonate.

    Abstract: A process for the preparation of 2-oxo-1,3-dioxolanes by reaction of epoxides with carbon dioxide in the presence of alkali iodides wherein at least one epoxy compound is reacted in the presence or absence of inert solvent either with a combination of A) at least one alkali iodide and B) at least one compound of the group a) polyol and b) an ether or polyether or, if the epoxy compound already has the structural features of the compounds Ba) and Bb), with the alkali iodide A) alone, at temperatures from 40 DEG to 180 DEG C. while introducing carbon dioxide at normal pressure or at slightly increased pressure, to form the corresponding organic carbonates. The 2-oxo-1,3-dioxolanes obtained are used for the preparation of synthetic resins, containing urethane groups, in the form of coatings of molded bodies.

    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.
