Procedure

A mixed metal catalyst comprised of potassium brassylate and aluminum stearate (1:1 molar ratio of K:Al) was employed for the depolymerization of poly(ethylene brassylate) at a 1.8 wt. percent level. An 81.6 percent yield of ethylene brassylate was obtained. Comparable yields are obtained when this mixed metal catalyst is used for the depolymerization of poly(ethylene sebacate) and poly(3-oxa-pentamethylene azelate).
