Abstract

método para inibição de polimerização de um monômero aromático de vinila e composição anti-polimerização de monômero aromático de vinila trata-se de métodos e composições para inibição de polimerização de um monômero aromático de vinila, tal como o monômero de estireno, durante o processamento ou a destilação em temperatura elevada do mesmo. as composições compreendem uma combinação inibidora de (a) uma hidroxilamina e (b) um radical livre estável mais um retardador que ou é; (c) dinitrobutilfenol ou (d) quinona metídeo. a razão de (a) para (b) varia de cerca de 5% (a) a 95% (b) a cerca de 95% (a) a cerca de 5% (b). as composições são adicionadas ao monômero aromático de vinila em quantidades suficientes para evitar a polimerização durante o processo de destilação. tipicamente, a combinação inibidora é adicionada ao monômero aromático de vinila em uma quantidade que varia de cerca de 10 até 150 ppm do monômero. retardadores são tipicamente adicionados em uma quantidade que varia de 50 a 1.500 ppm do monômero aromático de vinila.
