✦ Synopsis

Kinetics of neoprene thermal decomposition has been performed under dynamic conditions at different heating rates, between 5 and 80 8C/ min in a TG apparatus. The same kinetic model has been applied simultaneously to runs performed at different heating rates and different atmospheres allowing a good correlation of the weight loss data. A mechanism based on three independent reactions has been used to model the thermal decomposition. The first reaction is of an order close to two, and the other two reactions are of order below one, similar to other plastic materials. Different alternatives for the mathematical treatment for fitting TG data were considered. The accuracy of the calculated kinetic parameters was studied by means of a sensibility analysis.

## Abstract Rates of thermal decomposition of title compounds have been measured using a static reaction system. They undergo a unimolecular first‐order elimination to give arylnitrile and the corresponding substituted amides. The decomposition parallels that of __N__‐arylidenamino cyclic amide. Th
