A master batch was prepared by combining isooctyl acrylate (714.00 g), 2-hydroxyethyl acrylate (523.00 g), polymethylmethacrylate macromonomer (52.00 g) of ELVACITE™ 1010 available from ICI Acrylics), 2,2′-azobis(2-methylbutyronitrile) (2.60 g), ethyl acetate (1245.50 g) and isopropanol (45.50 g). The resulting solution was divided in equal portions and placed into six 1 quart (0.95 L) amber glass bottles. The bottles were purged for 2 minutes with nitrogen at a flow rate of 1 L per minute. The bottles were sealed and placed in a rotating water bath at 57° C. for 24 hours. At 24 hours the bottles were removed from the rotating water bath, unsealed, diluted with 76 g methanol per bottle, mixed until homogenous, and recombined into a 1 gallon (3.8 L) glass jar. The percent solids of the resultant copolymer was 40.5%. The inherent viscosity, I.V., (of a 0.15 g/dL solution of polymer in ethyl acetate measured at 27° C.) was 0.77 dL/g.
