Abstract

<B>PROCESSO PARA A INIBIçãO DA POLIMERIZAçãO DE UM COMPOSTO VINìLICO<D>. Um processo para se inibir a polimerização durante o transporte, armazenamento e/ou produção de ácido (met) acrílico ou um éster deste inclui a adição de um composto de N-oxil e água a um composto vinílico; ou a dissolução de um composto de N-oxil em água e a adição da solução a um composto vinílico em um processo de recuperação, purificação, e/ou síntese do composto vinílico. O processo pode inibir a polimerização do composto vinílico com eficácia.
