Abstract: PROBLEM TO BE SOLVED: To provide a simple process for producing an ester of α,β- monoethylenically unsad. mono- and dicarboxylic acids and a hydroxylated polycondensate. SOLUTION: An ester E having a low residual acid content is produced from α,β-monoethylenically unsatd. 3-6C mono- and dicarboxylic acids S and a hydroxylated polycondensate P by reacting the acids S with the polycondensate P or a monomer component and/or an oligomer component and/or a polymer component for producing the polycondensate P in the presence or absence of a solvent and/or an esterification catalyst and/or other additives while removing water formed by the reaction and then removing unreacted acids S by distillation. In the step of distillation, water is added to distillate the acids S.

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.

Abstract: Prepn of polyesterpolyols by polycondensation of multifunctional carboxylic acids with multifunctional alcohols is effected in the following 2 stages: (1) condensation at 150-250[deg]C under normal pressure or in a vacuum of up to 10 mbar to a prod. with acid number 2-10 mg KOH/g; and (2) addn. of an esterification catalyst and condensation at 250-290 (pref 260-275)[deg]C and under a vacuum of 1-50 mbar. Also claimed is prepn of opt foamed polyurethanes from polyisocyanates, polyols of mol wt 400-10,000 and opt also low mol chain extenders, blowing agents etc, with the polyol being obtd as per stages (1) and (2) above.
