Synthesis, kinetic studies and study of thermal and thermo-oxidative properties of thiol-containing compounds as polymer stabilizers

Kinetic patterns of radical polymerization of a fluorinated monomer have been synthesized and investigated, and optimal parameters for polymer production have been determined. The issues of using the obtained polymers as stabilizers of industrial polymer materials are considered. In particular, studies have been conducted on the effect of benzothiazole groups on the process of thermal oxidative degradation and thermal decomposition of polymers and copolymers. The study of the initial stage of depolymerization of polystyrene and the stabilized sample showed that when using an oligomeric stabilizer polythiobenzthiazole methacrylate, as well as a synergistic mixture of PTBTM and phenyl-β-naphthylamine, a relatively large stabilization effect is achieved compared with an industrial stabilizer.
