Abstract

Patente de Invenção: <B>INIBIçãO DE POLIMERIZAçãO DE ACRILATOS USANDO MISTURAS DE NITRÈXIDOS"<D>. Monómeros carboxílicos etilenicamente insaturados como ácido acrílico ou metacrílico ou seus ésteres são protegidos de polimerização prematura durante manufatura e estocagem na presença ou na ausência de água pela incorporação de um montante estabilizador eficaz de uma mistura de dois ou mais nitróxidos. Algumas dessas misturas proporcionam eficácia de estabilização sinérgica muito superior a resultados de estabilização obtidos pelo uso de cada nitróxido sozinho.
