Abstract:
1. Method for the manufacturing of a modified hyperbranched polyesteramide according to formula (1): D=(C 2 –C 24 ), aryl or (cyclo)alkyl aliphatic diradical, optionally substituted, wherein X 2 can be X 1 , and terminates with at least —H, and optionally also R 1 , R 2 , R 3 , R 4 , R 5 and R 6 may be H, (C 6 –C 10 ) aryl or (C 1 –C 8 )(cyclo)alkyl radical, OR 7 is derived from a hydroxy-, or amino functional monomer, oligomer or polymer, wherein R 7 can be aryl, alkyl, cycloalkyl, or the radical of polyethyleneoxide, polypropyleneoxide, polytetrahydrofurane, or a nylon oligomer, R 8 and R 9 may, independently of one another, be chosen from the group of, optionally hetero atom substituted (C 6 –C 10 ) arylgroups, or optionally heteroatom substituted (C 1 –C 28 ) alkylgroups and C(O)R 10 is derived from a monomeric, oligomeric or polymeric monofunctional carboxylic acid, characterized in that (a) the hydroxy-, or amino functional monomer, oligomer or polymer is contacted with a first molar excess of a cyclic carboxylic acid anhydride, forming a mixture of an acid functional ester respectively an acid functional amide and a cyclic carboxylic add anhydride; (b) the mixture is contacted with an amount of alkanediolamine, wherein the amount is a second molar excess with respect to the first molar excess.
