ABSTRACT:
A method of making aqueous solutions of polyesterimides and the resulting solutions are disclosed. The disclosed method is particularly adapted to making aqueous solutions of high molecular weight polyesterimides with low acid numbers. The resulting aqueous polymer solutions can also be made with high polymer solids content. Solubilization takes place utilizing a base to open imide bonds in the ester-imide polymer chain. The polymer solution has particular utility as a wire enamel.
