Abstract: The invention relates to a polyglycerol partial ester obtainable by esterification of a polyglycerol with a carboxylic acid mixture comprising at least one polyhydroxycarboxylic acid of a hydroxycarboxylic acid having 8 to 32 carbon atoms, at least one short-chain dicarboxylic acid having 2 to 16, preferably 6 to 14, particularly preferably 8 to 12, carbon atoms, at least one long-chain dicarboxylic acid having 24 to 44, preferably 30 to 40, particularly preferably 34 to 38, carbon atoms, and at least one fatty acid selected from linear, unsaturated and branched, saturated fatty acids having 14 to 24 carbon atoms, to a method for preparing polyglycerol partial esters, and to the use of corresponding polyglycerol partial esters as W/O emulsifier.

Abstract: The invention relates to a process for producing a porous polyurethane coatings, using a polyol ester as additives in an aqueous polymer dispersion, the process comprising the steps of a) providing a mixture comprising an aqueous polymer dispersion, a polyol ester, and an additive, b) foaming the mixture to give a homogeneous, fine-cell foam, c) adding at least one thickener to establish the desired viscosity of the wet foam, d) applying a coating of the foamed polymer dispersion to a suitable carrier, e) drying the coating. The invention further relates to a phosphorylated polyol ester.
