Abstract

"PROCESSO DE ADSORçãO DE INIBIDORES DE POLIMERIZAçãO DE MONÈMEROS ETILENICAMENTE INSATURADOS". A invenção refere-se a um processo de adsorção de inibidores de polimerização de monómeros etilenicamente insaturados, no qual se coloca em contato estes inibidores com uma alumina proveniente de uma conformação por coagulação em gotas ou por malaxagem-extrusão.
