Abstract: Water-dilutable dispersions of acrylate copolymers having a hydroxyl number of from 40 to 200 mg of KOH/g and an acid number of from 15 to 50 mg of KOH/g, obtained by free-radical copolymerization of a) from 5 to 40 parts by weight of at least one glycidyl ester of an aliphatic, saturated monocarboxylic acid which is branched in the alpha -position, b) from 0 to 30 parts by weight of at least one diester of an alpha , beta -olefinically unsaturated dicarboxylic acid, c) from 0 to 70 parts by weight of at least one vinyl aromatic hydrocarbon, where the molar amount of component c) is always greater than or equal to the molar amount of component b), d) from 0 to 60 parts by weight of an alkyl ester of an alpha , beta -olefinically unsaturated carboxylic acid, e) from 2 to 40 parts by weight of at least one alpha , beta -olefinically unsaturated carboxylic acid, where the molar amount of component e) is always greater than the molar amount of component a), f) from 5 to 40 parts by weight of at least one hydroxyalkyl ester of an alpha , beta -olefinically unsaturated carboxylic acid, where the polymerisation is carried out in the presence or absence of solvents, optionally with addition of a water-dilutable solvent, neutralisation and dilution with water. These dispersions are suitable as water-dilutable binders for stoving (baking) varnishes or stoving solid-colour top coats.

Abstract: Low-mol. wt. copolymers (I) with a wt.-average mol. wt. (Mw) of less than 3500 contain at least 20 wt.% of components with branched side chains, obtd. by the reaction of (aa) glycidyl ester(s) of satd. aliphatic monocarboxylic acids with a tert. or quat. alpha -C atom; and (ab) at least two unsatd. comonomers, at least one of which contains at least one COOH gp., under radical copolymerisation conditions. Also claimed are (i) prepn. of (I) by heating component (aa) to 210-260 degrees C and reacting with component (ab) (which contains at least 2.0 wt.% of a COOH gp.-contg. monomer) in the presence of radical initiator(s), to a degree of conversion of at least 95 (pref. at least 97.5) %; (ii) polymer mixts. contg. (I), obtd. by reaction of (aa) and (ab) as above in at least two time intervals with a constant temp. in each interval, using at least two different reaction temps., at least one of which is in the range 210-260 degrees C; (iii) polymer mixts. contg. (I) and other polymers etc.; (iv) binders for coating materials contg. (I) or the above polymer mixts.; (v) coating materials contg. binders as above and hardeners such as amino resins, capped or uncapped polyisocyanates or organic cpds. with acid and/or anhydride gps.

Abstract: Epoxide-amine adducts having a proportion by mass of at least 20% of aliphatic epoxide or amine units which comprise at least one tertiary or quaternary carbon atom are disclosed. The adducts are employed as binders for coatings of relatively high environment-friendliness, if desired, for example, in a mixture with other hydroxy-functional binders, and as reactive component in corresponding adhesive compositions and sealing compounds.
