The important role of polymer melt structure in intensive thermodegradation temperature or thermostability of polymer blends has been shown. The last characteristics depends on chemical constitution of polymer, compactness of macromolecular coil in melt and oxidizer diffusion type. The intensive thermodegradation temperature calculation according to the proposed model has been shown a good correspondence to experiment.
