Abstract: A polyurethane composition comprising: A) from 3 to 35% by weight of a polymeric composition comprising 1) at least one polymer and 2) at least one thermoset in amounts of from 0.5 to 50% by weight, based on the sum of A1) and A2), prepared by reaction in the polymer matrix A1) of a) at least one starting component containing NH2 groups and b) at least one starting component containing NCO groups, a) and b) having simultaneously or independently a functionality of ?2 and at least one starting component having a functionality of >2 being present in amounts of from 0.5 to 100% by weight, based on the weight of A2); B) from 15 to 45% by weight in the polymeric composition A), based thereon, of at least one amorphous and/or crystalline polyester having an OH number of from 10 to 250 mg KOH/g; C) from 7 to 25% by weight in the polymeric composition A), based thereon, of at least one curing agent based on blocked polyisocyanates, isocyanurates and/or uretdiones having a functionality of at least 1.

Abstract: Binders for coating materials that exhibit high flexibility and good hardness contain a polymer-modified resin, containing I) at least one hydroxy-functional polyester, and II) at least one polyacrylate having at least one hydroxy group or at least one carboxy group or both. The polyester I contains an alcohol component containing of from 0.5 to 80 mol % of dicidol.

Abstract: Binders for coating materials that exhibit high flexibility and good hardness contain a polymer-modified resin, containing I) at least one polyester having a hydroxyl group or a carboxyl group or both, and II) at least one glycidyl-containing polyacrylate. The polyester I contains an alcohol component containing of from 0.5 to 80 mol % of a dicidol fraction, and the resin is obtained by free-radical polymerization of the starting component(s) for the preparation of the polyacrylate II in the presence of the polyester I in at least one organic solvent.

Abstract: The invention relates to a polymeric composition prepared from a polymer and a thermoset, in which the thermoset was prepared in the polymer matrix from the starting components of the thermoset.

Abstract: A polyurethane composition comprising:

Abstract: An epoxy resin-polyammonium salt emulsion is based on a liquid epoxy resin, a latent curing agent, an emulsifier, and water. The emulsion is used in epoxy resin-cement mortars, in alkaline curing cement mixtures, and in adhesive compositions based on hydraulically setting alkaline cement binders.

Abstract: An epoxy resin-diammonium salt emulsion is based on a liquid epoxy resin, water, an emulsifier and a latent curing agent, wherein the emulsifier is(a) a polyvinyl alcohol obtained by saponification of polyvinyl acetate with a degree of hydrolysis of at least 70% and a molecular weight of at least 5,000,(b) a polyoxazoline having a molecular weight of 10,000-100,000, and/or(c) a copolymer of N-vinylpyrrolidone withvinyl esters of mono- or dibasic carboxylic acids of up to 6 carbon atoms,(meth)acrylic esters of mono- and dihydric alcohols of up to 6 carbon atoms,maleic, fumaric, crotonic acid and/orstyreneand wherein the latent curing agent is the salt from a(a) diamine of the formulaH.sub.2 N--CH.sub.2 --R--NH.sub.2 or H.sub.2 N--R--CH.sub.2 --R--NH.sub.2wherein R isan optionally substituted C.sub.4-9 -alkylene residue,an optionally substituted C.sub.6-9 -cyclo- alkylene residue, ora C.sub.

Abstract: Epoxy resin-diammonium salt emulsions are based on a liquid epoxy resin, a latent curing agent, and an emulsifier. The latent curing agent comprises diammonium oxalates and the emulsifiers are C.sub.8 - to C.sub.14 - alcohols and/or the adducts thereof with up to 10 ethylene oxide groups. A process for the production of such emulsions is provided. They are useful in epoxy resin mortars and epoxy resin-cement mortars, and for the sealing of concrete surfaces.
