  • Publication number: 20230303772
    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.
