Reaction Conditions

Reaction Steps

A mixed metal catalyst comprised of aluminum stearate and lithium stearate (molar ratio 1:1) was used for the depolymerization. For the reaction aluminum stearate (1.09 gram) and lithium stearate (0.36 gram) were blended in 70 grams poly(ethylene brassylate) at 200° C. The temperature was then raised to 314° C. while maintaining a vacuum of 0.05-0.1 mm Hg. Ethylene brassylate was obtained (40 mls during the first hour) in an 88.9 percent yield. Of the ethylene brassylate recovered, 90 percent of the product was obtained after 2 hours.
