Procedure
As set out hereinabove, the binder component of the dispersion of the invention is an organic polycarbonate polymer. The resulting polymer of the polymerization of 5-carbomethoxy-5-methyl-1,3-dioxan-2-one may be used as a component of the polymer binder. The polycarbonate polymer of 5-carbomethoxy-5-methyl-1,3-dioxan-2-one may be prepared as disclosed in Weilandt, K. D., Keul, H. and Hocker, H., Macromol. Chem. Phys. 197, 3851-3868 (1996). 5-Carbomethoxy-5-methyl-1,3-dioxan-2-one may be prepared via the reaction of 2,2-bis(hydroxymethyl)propionic acid with methanol to give methyl 2,2-bis(hydroxymethyl)propionate, which was then reacted with triphosgene in the presence of triethylamine to afford the desired product, 5-carbomethoxy-5-methyl-1,3-dioxan-2-one, as a white solid.
