Repeating Example X, a double metal salt was prepared except that sodium stearate was substituted for the potassium stearate and the ethyl cellusolve was replaced with diethylene glycol monoethyl ether. The resulting double metal salt NaAl(OC2H4OC2H4OC2H5)3 (OOCC17H35) was used as the catalyst for the continuous depolymerization of poly(ethylene brassylate) in accordance with the procedure and conditions of Example I. Ethylene brassylate was continuously produced and distilled from the reactor at a rapid rate and the overall yield was 73.2 percent. Comparable results are obtained using the double metal salt NaAl(OC2H4OC2H5)3 (OOCC6H5) obtained by the reaction of sodium benzoate and aluminum tricellusolve (Al(OC2H4OC2H5)3).
