Synergism of the action of some stabilisers against the destruction of polymer materials

The process of thermal-oxidative degradation polymer materials has been studied on the example polyethylene in presence quinones and / or nitroxyl radicals. synergistic effect positive action a mixture stabilisers from number radicals destructive established. It shown that rate significantly slowed down when an equimolecular 4-acetylamino-2,2,6,6-tetramethylhexahydropyridine-1-oxyl 2,6-di-tert-amyl-1,4-cyclohexadienone inhibitors introduced into polymer. kinetics initiated thermo-destructive oxidation absence studied. A mechanism joint based their interaction with breakage radical chains, as well for regeneration stabilisers, proposed.
