Synthesis of new methacrylates based on 6-phenylquinoline and their effect on the thermal degradation of polystyrene

In this work for the creation of polymers of special purpose six new quinolin-6-yl-phenylmethacrylates were synthesized by acylation of 3- and 4-hydroxyphenylquinolines with methacrylic acid chloroanhydride. The structure of the synthesized compounds was proved by spectral methods. The effect of new monomers as dopands on the polystyrene destruction was investigated. It was found that the investigated additives at covalent introduction into polystyrene weakly inhibit the process of its destruction, and additives containing nitro group - even contribute to its accelerated destruction.

Automated summary

This work focuses on the synthesis of six new quinolin-6-yl-phenylmethacrylates for the creation of polymers with special purpose. The structure of the synthesized compounds was confirmed using spectral methods. The study investigates the effect of these new monomers as dopants on the destruction of polystyrene. The results show that the additives weakly inhibit the process of polystyrene destruction when covalently introduced, while additives containing nitro group even accelerate its destruction.
