Abstract: The present invention relates to aqueous binder compositions comprising an aqueous polymer latex of a film forming carboxylated polymer and a branched polyetheramine polyol dissolved in the aqueous phase of the aqueous polymer latex, wherein essentially all of the amino groups in the branched polyetheramine polyol are tertiary amine groups. The present invention also relates to water-borne coating compositions containing such an aqueous binder composition.

Abstract: Disclosed herein is a branched polyester formed by an acid component, a diol component and a polyol component. The acid component includes an amino dicarboxylic acid of formula (I)




where R1 is hydrogen or a hydrocarbon having 1 to 20 carbon atoms. One or more carbon atoms can be replaced by oxygen, provided that the replaced carbon is not a primary carbon atom and, if more than one oxygen replaces carbon atoms, at least two carbon atoms are between adjacent oxygen atoms. The diol component includes a diol, the polyol component includes a polyol, and the acid component forms carboxylic acid ester groups with the diol and the polyol. The molar ratio of diol and polyol is between 2:1 and 1:2. Further disclosed are a process for preparing the branched polyester, a reaction product of the branched polyester with a polyisocyanate, and a method of using the reaction product.

Abstract: The invention relates to a method for the preparation of a hyperbranched polyester mixture obtainable by reacting a hydroxyl group containing carboxylic acid (B) with at least one carboxylic acid group and at least two hydroxyl groups with a diol (C) having a molecular weight of more than 100 g/mol, optionally in the presence of at least one further reactant, wherein the at least one further reactant is a polyol (A) having at least three hydroxyl groups under a reaction condition allowing ester and ether formation; and reacting the mixture resulting from step (a) with a hydrophobic carboxylic acid (D) resulting in the hyperbranched polyester mixture. The invention further relates to said hyperbranched polyester mixture and the use as wax inhibitor, as pour point depressant, as lubricant or in lubricating oils.
