Abstract: Radiation-curable urethane prepolymers are made from a mixture in which the isocyanate component contains two different trifunctional isocyanates or one tri- and one di-functional isocyanate, or the unsaturated polyol component contains at least two different unsaturated compounds with reactive hydroxyl groups and possibly other hydroxy compounds. A process for the production of radiation-curable, urethane group-containing prepolymers (PU) comprises reacting an isocyanate component (A) containing trifunctional isocyanate(s) (A1) and optionally difunctional isocyanate(s) (A2) with a polyol component (B) containing unsaturated compound(s) with at least one reactive hydroxyl group (B1) and optionally other OH group-containing compounds (B2), in which either (A) contains two different compounds (A1) or one (A1) and one (A2), or component (B) contains at least two different compounds (B1). Independent claims are also included for the following: (1) radiation-curable urethane prepolymers obtained by this process; (2) radiation-curable preparations containing prepolymers (PU) as above and possibly conventional additives etc.; (3) a process for coating substrates by applying PU or preparations containing PU to the substrate, removing any solvent; and hardening with UV or electron beam radiation; (4) coated substrates obtained by this process.

Abstract: A process for the production of esters (E) with a low content of residual acid from alpha , beta -mono-unsaturated 3-6C mono- or di-carboxylic acids (S) and hydroxyl group-containing polycondensates (P) comprises (a) reacting (S) and (P) (or the monomeric, oligomeric and/or polymeric components which form P) optionally in the presence of solvent and/or esterification catalyst and/or other additives and removing the water produced, and (b) removing unreacted (S) by distillation in the presence of added water.
