Patent

CA 2353179

Described are methacrylate or acrylate binders e.g. obtainable by the steps of (i) generating OH-precursors from at least one aromatic polyester, and (ii) reacting said OH-precursors of step (i) with methacrylic acid and/or acrylic acid to form a respective ester, whereby step (i) comprises reacting an aromatic polyester, or a mixture of aromatic polyesters with at least one polyol and/or at least one aminopolyol to generate hydroxy terminated oligomers. Optionally, a modified product can be obtained by performing a further reaction in step (i), namely by reacting said hydroxy terminated oligomer with at least one polycarboxylic acid and/or at least one polycarboxylic anhydride to generate said hydroxy terminated binder precursor oligomer.
