Versuchsvorschrift

Sodium brassylate (0.33 g) and aluminum stearate (1.09 g) were added to 70 g poly(ethylene brassylate) and the mixture heated at 200° C. until a homogeneous viscous mass was obtained. The molar ratio of sodium to aluminum was 2:1. The temperature was then increased to 312° C. and the pressure reduced to 0.3-0.5 mm Hg. The depolymerization reaction was complete in about 3 hours and 88.1% yield ethylene brassylate was obtained.
