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 weight 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).
