Abstract

A method for production of a carboxy terminated dendritic polyester is disclosed. Said process comprises ring opening addition of at least one anhydride of a di, tri or polyfunctional aromatic and/or cycloaliphatic carboxylic acid to at least one hydroxy functional dendritic polyester having a hydroxyl value of at least 50 mg KOH/g. Said ring opening addition is performed at a molar ratio said anhydride to hydroxyl groups of between 0.2 to 1 and 1 to 1 and at a reaction temperature of 130-150 DEG C. Yielded carboxy terminated dendritic polyester has a glass transition temperature of at least 35 DEG C. The invention relates in further aspects to a powder coating composition comprising the carboxy terminated dendritic polyester obtainable by said process and the use of said carboxy terminated dendritic polyester in a resin composition.
