실험 절차

Isooctyl acrylate (54.9 Kg), N-vinyl-2-pyrrolidone (5.4 Kg), and ethyl acetate (93.6 Kg) were charged into a 75 gallon (285 liter) stainless steel reactor. The mixture was deoxygenated and heated to 55° C. After 5 minutes at 55° C., azobisisobutyronitrile (30 g) premixed in ethyl acetate (1 Kg) was charged to the reactor. Additional portions of azobisisobutyronitrile (30 g) premixed with ethyl acetate (1 Kg) were added 4 hours after the start of the reaction and again at 8 hours. The temperature was maintained at 55° C. throughout the reaction. The reaction was continued until complete. An antioxidant (61 g, IRGANOX™ 1010, Ciba-Geigy Corp.) and heptane (66.3 Kg) were added to the reactor and the contents mixed until homogeneous. The final copolymer had a measured inherent viscosity of 1.67 deciliter/g in ethyl acetate.
