Abstract: For the preparation of elastic flexible polyurethane foams with improved breaking elongation and very good setting behavior as well as densities from 7 to 120 grams per liter, organic polyisocyanates are reacted in the presence of blowing agents, catalysts and, optionally, auxiliaries and/or additives with polyols based on polyoxyalkylene polyols having terminal oxyethylene blocks of a degree of oxyethlation of 1 to 13 and which have a content of primary hydroxyl groups at the corresponding degree of oxyethylation equal or exceeding the value of curve A in the Figure in which curve A describing the relationship of the content of primary hydroxyl groups with the degree of oxyethylation.

Abstract: Elastic, radiation-crosslinked polyurethane foams are obtained by reacting organic polyisocyanates, polyols and acrylic acid and/or methacrylic acid derivatives containing at least one bonded Zerewitinoff-active hydrogen atom, preferably adducts of acrylic acid and/or methacrylic acid and epoxides in a carboxyl:epoxide group ratio of approximately 1:1, in the presence of blowing agents, catalysts and optionally auxiliaries and additives, and subsequently irradiating the foams with electrons at an acceleration voltage of at least 50 kV and a maximum dosage of 1000 kJ/kg.

Abstract: A process for coating electrically conductive objects comprising A. immersing said object as the anode of an electric current in an aqueous polyurethane dispersion prepared by (1) forming a polyurethane solution by reacting an organic polyisocyanate in the presence of an organic solvent with (a) an acrylic ester diol having a molecular weight of between 146 and 3,000; (b) an organic polyhydroxyl compound other than (a) having a molecular weight between 400 and 5,000 selected from the group consisting of polyester, polyols, polyether polyols, polycarbonates, polylactones, and mixtures thereof; and (c) a chain extender selected from the group consisting of diols, triols, diamines, aminoalcohols, having a molecular weight between 62 and 400, water, and mixtures thereof; (2) forming an anionic polyurethane addition product by reacting said polyurethane solution with a mercaptocarboxylic acid salt in the presence of a solvent; (3) adding water; and (4) removing the organic solvent, and B. passing an electric current between the anode and a cathode which is also dispersed in said dispersion, and C. irradiating said object with ultraviolet radiation or electron rays. The process can be used for coating metals such as iron, steel and aluminum.

Abstract: The invention relates to polyurea-polyol dispersions with a long shelf life which contain a) from 2 to 35 % by weight, based on the entire dispersion, of a polyurea prepared from modified aliphatic and/or cycloaliphatic polyisocyanates and aliphatic amines and/or optionally substituted monoaminobenzenes or modified aromatic polyisocyanates and aliphatic amines and, b) from 98 to 65 % by weight, based on the entire dispersion, of a bifunctional to hexafunctional polyol having a hydroxyl number of from 20 to 600. The dispersions are prepared by in-situ reaction of the modified polyisocyanates with aliphatic amines and/or monoaminobenzenes in polyols, have, at a polyurea content of 10 % by weight, a viscosity at 25 DEG C of from 1000 to 2500 mPa.s and a clear point of from 100 to 300 DEG C and are particularly suitable for the production of polyurethane foams.
