Abstract

"PROCESSO DE ESTABILIZAR OS éSTERES DO áCIDO (MET)ACRìLICO". Em um processo para estabilizar os ésteres de ácido (met)acrílico contra a polimerização indesejável de radical, uma mistura de inibidores de polimerização que contenha pelo menos uma radical nitroxila e/ou pelo menos um composto orgânico com pelo menos um grupo nitroso e pelo menos uma p-fenileno diamina é adicionada à mistura a ser estabilizada.
