Studies on the thermal degradation of butyl rubber

Abstract

Butyl rubber was pyrolysed under an inert atmosphere in a furnace-type pyrolyser at 400°C. The pyrolysate was trapped cryogenically and analysed by GC, GC/MS and GC/FT-IR. Based on these data, a mechanism for the thermal degradation of butyl rubber is proposed. The effect of temperature on the reative yields of the major decomposition products was also studied. © 1993.
