Abstract: 1. A process for preparing an elastic, compact or cellular polyurethane by reacting a) an organic polyisocyanate with b) an organic polyhydroxy compound in the presence of c) a catalyst and optionally d) a chain extending or crosslinking agent, e) a blowing agent, f) an assistand and/or an additive, wherein polyhydroxy compound b) comprises to an extent not less than 30% by weight, based on total component b), a di-, tri- or tetrafunctional polyether polyester polyol having a hydroxyl number of from 10 to 200 and having been prepared by esterification of i) a di-, tri- or tetrafunctional polyetherol having a hydroxyl number of from 15 to 250 with a carboxylic anhydride in the presence of N-methylimidazole and/or triethylenediamine as a catalyst to give a carboxylic monoester and subsequent ii) alkoxylation of the carboxylic monoester with an alkylene oxide in the presence of a mixture of N-methylimidazole and/or triethylenediamine and triphenylphosphine and/or a thiodialkylene glycol as a catalyst, the amount of catalyst being from 0.05 to 2.0 parts by weight, based on 100 parts by weight of the mixture of polyol and carboxylic anhydride or on 100 parts by weight of carboxylic monoester.

Abstract: In order to prepare polyester or polyetherpolyester polyols, polyols, preferably di- to hexafunctional polyether polyols having hydroxyl numbers from 15 to 250 are esterified with at least one carboxylic acid anhydride, preferably phthalic acid anhydride, in the presence of N-methylimidazole, triethylenediamine, and/or triphenylphosphine as catalysts to form a carboxylic acid half-ester, and said half-ester is then oxyalkylated with at least one alkylene oxide, preferably ethylene oxide, in the presence of N-methylimidazole, triethylenediamine, triphenylphosphine, thiodialkylene glycol, employing a mixture of at least two of the compounds cited as catalysts.

Abstract: Binder for powdered coating compsns. consists of a mixt. contg. (A) 70-95 (80-90) wt.% polyester resin having vitreous transition temp. 50-60 degrees C and an acid no. 100-180 and (B) 5-30 (10-20) wt.% of >=1 bifunctional epoxide resin having epoxide no. 0.2-0.6 (mole epoxide/100 g), and has vitreous transition temp. 40-50 degrees C and melt viscosity 104-107 m pas at 120 degrees C. Compsns. may contain standard additives, e.g. pigments, fillers, crosslinking catalysts and/or flow control agents. The compsn. is useful for coating metallic surfaces, e.g. steel, cast iron, non-ferrous metals or Al, and non-ferrous surfaces, e.g. ceramic, wood, glass. Stoving can take place at 200 (180-190) degrees C, without generation of smelly decompsn. products. Coatings have good flow and props.

Abstract: Production of pigmented resin powders by finely dispersing dispersions of pigments in solutions of polymeric materials in at least one organic solvent in water containing a protective colloid while supplying mixing energy, and removing the solvent. A preferred method is to introduce one or more jets of water containing protective colloid at the rate of 5 to 100 m/sec into animpulse exchange chamber together with the dispersion issuing in the immediate vicinity of the orifice(s), and to remove the solvent. The method avoids crosslinking and provides pigmented resin powders of consistently reproducible color which are suitable for conventional powdered-resin coating methods.
