Abstract: The instant invention is broadly directed to novel hydroxyl containing compositions and the use thereof in producing polyurethane resins. The novel products are produced by mixing a halogenated bisphenol with a hydroxypolyester and thereafter alkoxylating the mixture.

Abstract: A water-insoluble condensation product of a polyalcohol, a dicarboxylic acid, from 5 to 35% by weight of a saturated monohydric alcohol having from 1 to 3 carbon atoms and, optionally, a monocarboxylic acid, said condensation product being soluble in lacquer solvents and useful for producing stoving lacquers.

Abstract: Polymer mixtures consisting essentially ofA. a polyethylene with a melt index of above 15 g/10 min,B. a graft polymer of an ethylene/(meth)acrylic acid copolymer as graft substrate and grafted polymerized units of .epsilon.-caprolactam, andC. a poly-.epsilon.-caprolactam.

Abstract: Aqueous polyester and alkyd resin stoving lacquers containing .epsilon.-caprolactam as a so-called reactive diluent and small quantities of volatile organic solvents yield excellently hard coatings which are not brittle.

Abstract: Non-aqueous polyester and alkyd resin stoving lacquers containing .epsilon.-caprolactam as a so-called reactive diluent with a high solids content and containing correspondingly small quantities of volatile solvents and yield excellently hard coatings which are not brittle.

Abstract: A process for the production of water-dilutable binders based on air-drying short-oil alkyd resins acidified by semiester formation with dicarboxylic acid anhydrides which alkyd resins have acid numbers of from 30 to 70 and hydroxyl numbers of from 40 to 120 and a content of natural unsaturated fatty acids in an amount of from 15 to 50 % by weight and of a co-condensed natural-resin-modified phenol resol resin in an amount of from 2 to 10 % by weight, characterized in that 1. the molar composition of the alkyd resin before semiester formation corresponds to a polyalcohol/polycarboxylic acid (anhydride)/monocarboxylic acid ratio of 1 : (0.5-1) : (0.3-1), and 2. polyalcohols, polycarboxylic acids resp. their anhydrides, monocarboxylic acids and phenolic resins are co-condensed in a single process stage, followed only by semiester formation with dicarboxylic acid anhydrides.

Abstract: Stoving lacquer systems having a high solids content contain a binder consisting of carboxyl and hydroxyl group-containing polyester or alkyd resin including an .epsilon.-caprolactone as a "reactive diluent", and an aminoplast resin as a cross-linking agent.

Abstract: Liquid stoving-lacquer systems based on oil-free polyesters obtained by reacting polybasic carboxylic acids or their anhydrides and 2-ethylpropane diol-1.3 and optionally additional polyhydric alcohols, are highly compatible with melamine resins.

Abstract: The invention relates to a pulverulent coating material prepared from a polyester which contains free carboxyl groups of succinic acid and cross-linking agents which react with carboxyl groups at elevated temperatures.

Abstract: Powdered coating agent for use in the sprayed powder process comprising a mixture ofA. free hydroxyl groups containing copolymers having been reacted with an acid anhydride;B. a cross-linker such as triglycidyl isocyanurate or bis- or tris-oxazolines and optionallyC. auxiliary agents such as pigments and levelling agents.The copolymer contains polymerized units of30 to 85% by weight of styrene or derivatives thereof or methylmethacrylate or mixtures thereof;5 to 60% by weight of acrylic or methacrylic esters excepted methylmethacrylate and10 to 30% by weight of hydroxyalkylester of acrylic or methacrylic acid, said copolymer having been reacted with an aliphatic or cycloaliphatic dicarboxylic acid anhydride;4 to 20 parts by weight of the cross-linker are employed for 96 to 80 parts by weight of the acidified copolymer.
