Abstract

PROCESSO PARA ESTABILIZAçãO DE MONÈMEROS OLEFINICAMENTE INSATURADOS. A presente invenção refere-se a um processo para estabilização de monómeros olefinicamente insaturados, caracterizado pelo fato de que uma composição contendo um agente de retardo, que apresenta um solvente e uma quinona-metida como agente de retardo, é adicionada a um monómero olefinicamente insaturado ou mistura de monómeros, que apresenta pelo menos um monómero olefinicamente insaturado, bem como à composição monómera resultante do mesmo.
