Abstract:
A method of preparing a polymer composition and coating a surface with the polymer composition, said method comprising the steps of:providing a dispersion including a quantity of a compound according to the formula: wherein each X is individually selected from the group consisting of NR2 and phenyl groups, where each R is individually selected from the group consisting of hydrogen, alkoxyalkyl groups, carboxyl groups, and hydroxymethyl groups; adding to said dispersion from about 0.001-1 moles of an acid per liter of said dispersion; heating said dispersion to a temperature of at least about 70Â° C. for at least about 2 hours to yield the polymer composition; mixing the resulting polymer composition with a solvent so as to form an anti-reflective coating; and applying said anti-reflective coating to the surface of a substrate to form a layer of anti-reflective coating on said substrate surface.
