- composition of the additive mixtures; electron spin resonance; results of the fire retardancy tests of the PP-based formulations; characteristics of chars resulting from the thermal treatment of the additive mixtures; analysis of the free radicals 'trapped' in the carbonization products; characteristics of the ESR spectra of chars resulting from the thermal treatment of the additive mixtures; assignments of CP and DD-MAS NMR 13C spectra of the APB-PER system versus HTT
