A 1-liter, four-necked, round bottomed flask equipped with a mechanical stirrer, two addition funnels, a distillation head with a variable takeoff, a thermometer, a nitrogen inlet, and a heating mantle atop a thermosensor-controlled pot lifter is charged with 300 g of propylene glycol. This heel charge is heated to 150° C. under nitrogen. The monomer charge (135 g styrene, 165 g methacrylic acid, and 3 g mercaptoethanol) is gradually charged over 5 hours. Simultaneously, the initiator solution (9.0 g of 70% t-butyl peracetate) is added over the same period. After completion of the feeds, an additional 0.9 g of t-butyl peracetate solution is added and the batch held at150° C. for another hour.
