Katalysatoren beim thermischen Abbau von Polymeren, 1. Über den katalytischen Abbau von Polypivalolacton

The ability of different metal oxides and acetates to catalyze the thermal degradation of poly(pivalolactone) into cyclic oligomers has been investigated. Magnesium oxide was found to be the most active catalyst which converts poly(pivalolactone) completely into oligomers within less than two hours at 547 K. The influence of temperature and catalyst concentration and the distribution of cyclic oligomers is discussed.
