    摘要： A polyimide powder particularly suitable for the production of moldings by high pressure sintering is prepared by mixing a solution of an aromatic polyimido-acid, obtained by a conventional process and having an intrinsic viscosity of 1.5 to 2.5 dl/g, in an aprotic dipolar organic solvent, with a water-entraining agent, heating the mixture to the boiling point of the entraining agent, azeotropically distilling off the water formed, filtering off the polyimide powder which precipitates, washing it if appropriate, and drying it.

    摘要： Surface-coating binders based on a copolymer which contains carboxyl groups, blocked isocyanate groups, hydroxyl groups and ether groups, and which, due to partial or complete salification with ammonia or with an organic base, is water-soluble or water-dispersible.This copolymer contains, as copolymerized units, one or more .alpha.,.beta.-olefinically unsaturated carboxylic acids of 3 to 5 carbon atoms or one or more half-esters of an .alpha.,.beta.-olefinically unsaturated dicarboxylic acid of 3 to 5 carbon atoms, an N-(1-alkenyl) isocyanate blocked with a CH--, OH-- or NH-acidic blocking agent, an adduct of an epoxy resin, based on bisphenol A and epichlorohydrin and having a molecular weight of from 380 to 3,500, with an olefinically unsaturated alcohol of 3 to 20 carbon atoms, and one or more other copolymerizable olefinically unsaturated compounds, and has a mean molecular weight of from 1,000 to 20,000 and an acid number of from 35 to 150 mg of KOH/g.The novel surface-coating binder is useful for the anodic electrocoating of metallic articles.

    摘要： Polyadducts, free from epoxide groups, are obtained from ammonia and epoxide compounds by reacting 1 mole of ammonia with from 1.2 to 2.0 equivalents of epoxide, so that if diepoxide compounds are used products of the general formula (I) ##STR1## are obtained, while if triepoxides and/or tetraepoxide compounds are used, by themselves, or together with diepoxide compounds, products of the general formula II ##STR2## are produced; in these formulae, the E.sup.1 's are identical or different hydroxyl-containing divalent radicals and the E.sup.2 's are identical or different hydroxyl-containing trivalent or tetravalent radicals, resulting from the opening of the oxirane rings of epoxide compounds containing two, three or four epoxide groups in the molecule, n.sup.1, n.sup.3 and n.sup.5 are from 0 to 3, n.sup.2 and n.sup.4 are from 1 to 3 and X is 0 or 1, and one or more of the divalent radicals E.sup.1 in the general formula (II) may or may not be replaced by polyvalent radicals E.sup.2.The novel polyadducts can be modified by reaction with aldehydes, ketones, monoepoxide compounds, carboxylic acids, carboxylic acid esters or isocyanates, or by protonation with an acid, and may be used, for example, for the cathodic electrocoating of metallic articles.
