실험 절차

To demonstrate the improved yields and increased reaction rates obtained utilizing the mixed metal catalysts of this invention, batch polymerizations were identically conducted using (a) a mixed metal catalyst comprised of aluminum stearate and sodium stearate (1:1 molar ratio), (b) aluminum stearate catalyst, and (c) lead stearate catalyst. These reactions were conducted in accordance with the procedure employed in Example II utilizing 74 grams poly(ethylene brassylate) and 0.5 mole percent of the catalyst. Reactions were carried out at 310°-320° C. and 0.1-0.5 mm Hg. for four hours. The amount of distillate (crude ethylene brassylate) recovered was recorded after the first hour of reaction. With the mixed metal catalyst, 45 mls. ethylene brassylate was obtained after 1 hour and the overall yield was 95.9%. With the aluminum stearate, 36 mls. crude ethylene brassylate was obtained in the first hour and the overall yield was only 78%. Using lead stearate only 25 mls distillate was obtained after 1 hour and the yield of crude ethylene brassylate was 69.1%.
