Abstract: Emulsifier-free aqueous polyurethane dispersions are prepared by reacting (a) dihydroxy compounds, (b) diisocyanates and (c) chain extenders to give a prepolymer having terminal isocyanate groups, then reacting the prepolymer with (d) salts of aliphatic aminocarboxylic or -sulfonic acids or amino-containing or hydroxyl-containing tertiary ammonium salts, dispersing the resulting polyurethane in water and, if required, removing the organic solvent by distillation. In the process, an organic condensation resin which is dissolved in a solvent is admixed before the polyurethane obtained is dispersed in water.

Abstract: The invention relates to a process for producing foams that contain urethane groups in the presence of oligomers containing a plurality of fluoroaliphatic side groups and having a fluorine content from 5 to 30% by weight as surface-active auxiliary for improving the emulsifying effect, for regulating the cell structure and/or stabilising the foam, to the foams produced by the process, and to the use of the oligomers containing a plurality of fluoroaliphatic side groups and containing from 5 to 30% by weight of fluorine as foam stabiliser and/or cell regulator for producing cellular polyisocyanate polyaddition products.

Abstract: 1450906 Polyurethane layers; photopolymerizing unsaturated monomers BASF AG 3 Dec 1973 [4 Dec 1972] 55919/73 Headings C3R and C3P Polyurethane layers are prepared by adding a compatible monomer having at least two photocross-linkable C-C multiple bonds or a compatible monomer mixture comprising at least 50% by weight of one of such monomers and not more than 50% by weight of a photopolymerizable monoethylenically unsaturated monomer, and optionally also a photopolymerization initiator, to a liquid polyurethane elastomer forming reaction mixture comprising (A) (i) a polyether, polyester, hydroxypolyether urethane or hydroxypolyester urethane or a mixture thereof with a polyalcohol and/or a diamino and (ii) a diisocyanate or (B) (i) a prepolymer of a hydroxyl compound as defined in (A) and a diisocyanate and (ii) a polyester, polyether, hydroxypolyester urethane, hydroxypolyetherurethane, polyhydric alcohol, or diamine or a mixture of two or more thereof, the resulting mixture containing a major amount of the polyurethane elastomer-forming reaction mixture, applying the resulting mixture to a substrate to form a layer, irradiating the layer with electromagnetic radiation of wavelength less than 0À7 Ám to effect photocrosslinking of the monomer(s) and gelling of the layer and thermally curing the so-treated layer. The layer is suitably formed on a continuously moving substrate and has a thickness of from 0À2 to 5 mm. Conventional polyurethane elastomer-forming reactants are used. The monomer having at least two C-C multiple bonds is preferably an olefinically poly-unsaturated carboxylate, for example a diester of a C 2-6 aliphatic diol and acrylic or methacrylic acid, a triester of a C 3-10 aliphatic triol and acrylic or methacrylic acid, a divinyl ester of a C 2-8 dicarboxylic acid, a diallyl ester of a C 2-8 dicarboxylic acid and a vinyl ester or allyl ester of a C 3-5 olefinically unsaturated monocarboxylic acid. The unsaturated monomers are preferably used in amounts not exceeding 10% weight of the reaction mixture.

Abstract: Laminates for the production of relief plates for flexographic printing, by imagewise exposure and washing out with a developer solution have, on a base optionally provided with an elastomeric layer, a photo-crosslinkable layer containing a photoinitiator and consisting of a polyurethane elastomer which has been prepared in a special manner from an aliphatic saturated polyesterglycol, an aliphatic diisocyanate, but-1-ene-3,4-diol and, if desired, another diol and which has a Shore A hardness of 30 to 90 DEG in the photo-crosslinked state, the elastomer being optionally mixed with a photo-crosslinked monomer.
