Abstract: A process is provided for production of vicinal alkylene glycols by hydrolysis of an epoxyalkane having from 6 to 24 carbon atoms in the presence of water and a basic catalyst and under carbon dioxide pressures of from 100 to 300 bars and temperatures of from about 200.degree. C. to 350.degree. C. Also disclosed are homogeneous mixtures of epoxyalkanes and/or vicinal alkylene glycols having from 6 to 24 carbon atoms, water, a basic catalyst and carbon dioxide in an amount corresponding to a carbon dioxide partial pressure of from about 100 to 300 bars, provided at temperatures from about 200.degree. C. to 350.degree. C. The process provides high yields, selectivities and reaction velocities and the resulting products are of high purity.

Abstract: Self-curing cationic amide-group-containing aminourea resins are disclosed, if necessary with urethane groupings, which are the reaction product of at least(A) a polyaminoamide which has been produced from(1) one or more predominantly higher fatty acids and one or more alkylene or polyalkylene-polyamines and/or(2) dimer fatty acids, if necessary in mixture with predominantly higher, substantially unsaturated fatty acids, and one or more alkylene- or polyalkylene-polyamines, and additionally partially contains cyclic amidine-groupings produced under splitting off of water and, if necessary, amino-groups blocked by ketimine,(B) a diisocyanate and, if necessary, of(C)(1) a primary and/or secondary allyl- or methallylamine and/or(2) one or more saturated primary and/or secondary aliphatic, cycloaliphatic, heterocyclic or aromatic amines and/or(3) an allyl- or methallyl-alcohol and/or(4) one or more cyclic or polycyclic alcohols, which are olefinically unsaturated in their cyclic or polyclicic ring systems, and/or

Abstract: Method for the crosslinking of cathodically depositable coating agents, optionally containing pigment, dyestuff, filler, solvent, varnish adjuvant or additional crosslinking components, based upon a water-soluble or -dispersible nitrogen based cationic resin, at least partially present as salt, in which a cationic resin of molecular weight greater than 1000, containing 2 to 20 equivalents of double bonds per 1000 g, is contacted with sulfur and/or one or more sulfur-containing vulcanization acceleration. The coating mixture is then electrophoretically deposited upon an object, and hardened at temperatures above 120.degree. C. The resin may contain tertiary atoms of carbon, and also one or more sulfur-free vulcanization accelerators may be used.

Abstract: Waterdispersible cationic resins are formed by reacting the components comprising at least(A) an epoxidized polydiene,(B) a bisglycidylether of a polyphenol,(C) an amide compound, which is formed by one or more higher, substantially multiply unsaturated fatty acids and a polyamine and which may comprise a ketimine group or a hydroxy group, and possibly(D) an organic secondary amine and/or(E) a partially and/or fully masked polyisocyanate, which product comprises excess epoxide groups and carbon-carbon double bonds and which resins can be made waterdispersible with an acid under formation of cationic groups. A composite is provided comprising the cationic resin superposed on a conducting substrate and a method is described for forming the composite.

Abstract: A catephoretically depositable aqueous coating composition is disclosed which is based on(A) 100 parts by weight of an at least partially neutralized reaction product of an epoxy groups-containing compound and an amine and(B) 5-50 parts by weight of an at least partially blocked polyisocyanate,in which composition the constituents A and B may be chemically combined, wherein the aminated epoxy compound is the reaction product of(1) 40-90 parts by weight of an epoxidized (co)polymer, i.e. a homopolymer or copolymer, having an epoxy number of 50-400 of a (cyclo)alkadiene, i.e. alkadiene or cycloalkadiene, containing 4-12 carbon atoms, which (co)polymer has an average molecular weight of 400-12,000, and(2) 60-10 parts by weight of a compound having 1-30 carbon atoms and having at least one primary or secondary amino group.The invention also relates to a method for the preparation of said aqueous coating composition and to method of depositing same.
