Polystyrene is one of the most widely used plastics. The materials based on it are used in almost all branches of engineering and human’s daily life. Therefore, the creation of new highly effective thermal stabilizers for polystyrene remains as the actual task of polymer chemistry.
Combining fragments of basic industrial monomer with the modifiers in the polymer matrix provides the ability to control performance properties of obtained materials. In this work we report synthesis of new methacrylic monomers based on aurones and study of their thermostabilizing properties. The prospects of the practical application of new stabilized polystyrene are discussed.

Novel monomers and polymers were synthesized and their structure determined by NMR and UV-spectroscopy. Copolymerizations were carried out in ethyl acetate with AIBN as initiator. Copolymers were characterized by NMR.
