The degradation of polybutadiene by heating in inert atmosphere at various temperatures for different time intervals was characterized by i.r. and 1H n.m.r, methods. It was established that by i.r. analysis it is possible to assess both the temperature and the duration of the heating to which the sample had been subjected.
