Summary:The influence of succinimidophenylmethacrylate derivatives on the polystyrene thermal stability in argon is assessed by dynamic thermogravimetric analysis. The monomers (1 or 3 mol%) prepared by Diels--Alder reaction have been introduced into polystyrene by means of the copolymerization reaction. The decomposition products of polystyrene with additions have been investigated by thermal desorption analysis coupled with mass spectrometry. During the heating of polystyrene with additions, the retro-Diels--Alder reaction produces dienes and dienophiles which react with macroradicals and thus inhibit the radical chain process of polymer thermal decomposition. The inhibiting effect of the succinimidophenylmethacrylate derivatives is determined by the temperature range of the retro-Diels--Alder reaction. [PUBLICATION ABSTRACT]
