Abstract
"PROCESSO DE ADSORçãO DE INIBIDORES DE POLIMERIZAçãO DOS 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, a referida alumina apresentando um volume de poros de diâmetro superior a 100 Å, de pelo menos 0,20 ml/g, preferivelmente pelo menos 0,25 ml/g, ainda mais preferivelmente pelo menos 0,30 ml/g, e uma superfície específica de pelo menos 30 m²/g, preferivelmente pelo menos 60 m²/g, ainda mais preferivelmente pelo menos 80 m²/g.
