摘要：
Regularities of the change of the network structure in the course of thermal degradation of network polyurethanes have been determined from the data on kinetics of accumulation of the sol fraction and evolution of its MMD. The urethane group in the network point is shown to be a site of the most probable ruptures. the two-stage scheme of this process is proposed. The relation of MMD of the sol fraction with the length distribution of chains in a network is assumed.
