The process of thermal-oxidative degradation of polymer materials has been studied on the example of polyethylene in the presence of quinones and/or nitroxyl radicals. The synergistic effect of the pos. action of a mixture of stabilizers from a number of quinones and nitroxyl radicals on the destructive process of polyethylene has been established. It has been shown that the rate of degradation has significantly slowed down when an equimol. mixture of 4-acetylamino-2,2,6,6-tetramethylhexahydropyridine-1-oxyl and 2,6-di-tert-amyl-1,4-cyclohexadienone inhibitors has been introduced into the polymer. The kinetics of the initiated thermo-destructive process of polyethylene oxidation in the presence and absence of stabilizers has been studied. A mechanism of joint action of stabilizers based on their interaction with radicals and the breakage of radical chains, as well as a mechanism for the regeneration of stabilizers, has been proposed. In the experiment, the researchers used many compounds, for example, 4-Acetamido-2,2,6,6-tetramethylpiperidine 1-oxyl (cas: 14691-89-5Category: piperidines).
4-Acetamido-2,2,6,6-tetramethylpiperidine 1-oxyl (cas: 14691-89-5) belongs to piperidine derivatives.Piperidine is a key saturated heterocyclic scaffold found in several of the top-selling small molecule pharmaceuticals and natural alkaloids, with a diverse range of biological activities. Several piperidine alkaloids isolated from natural herbs, were found to exhibit antiproliferation and antimetastatic effects on various types of cancers both in vitro and in vivo for example Piperine, Evodiamine, Matrine, Berberine and Tetrandine.Category: piperidines
