Abstract
Thermal degradation of methyl and ethyl cyanoacrylate polymers of number‐average molecular weights 370–1350 is shown to proceed by depolymerisation at temperatures in the range 140°–180°C. Under the conditions of the thermogravimetric analysis technique employed, weight loss kinetics appear to be governed by diffusion of monomer vapour through the liquid sample. A mathematical model of this process is postulated.
