Abstract

"PROCESSO DE POLIMERIZAçãO PARA A PREPARAçãO DE POLìMEROS DE ANIDRIDO". Um processo para a preparação de anidrido em solventes de hidrocarboneto aromático usando um sistema de iniciador de composto amina/peróxido de dialquila é exposto. O composto amina permite um uso mais eficiente de iniciadores de radical livre, ao mesmo tempo em que alcança polimerizações de elevada conversão de monómero, comparado a sistema de iniciador convencionais, particularmente na preparação de polímeros de anidrido maleico.
