Abstract
Exemplary embodiments provide compositions for erasable media and methods of forming polymers for erasable media. The method can include providing a first monomer, the first monomer including one or more alkoxylated bisphenols and adding at least one second monomer and a catalyst to the first monomer to form a mixture at a first temperature, the second monomer selected from the group consisting of an organic diacid, a dialkyl ester of the organic diacid, and combinations thereof. The method can also include melt condensing the mixture by increasing the temperature from the first temperature to a second temperature over a first amount of time to form one or more polymers, wherein the one or more polymers has an acid value in the range of about 0.1 mg-KOH to about 12 mg-KOH.
