Abstract

"PROCESSO DE PRODUZIR UM POLìMERO, E, ESTABILIZADOR". Um processo de produzir um polímero compreende as etapas de formação de uma mistura da reação homogênea que compreende pelo menos um monómero polimerizável de adição, um fluido supercrítico e um estabilizador, em que o estabilizador compreende uma cadeia que é solúvel no fluido supercrítico e um grupo terminal funcional que não é polimerizável por um mecanismo de radical livre e polimerização pelo menos de um dito monómero na mistura da reação. Em um sistema preferido para a polimerização de monómeros acrílicos, o fluido compreende dióxido de carbono supercrítico e o estabilizador compreende um perfluoropoliéter funcionalizado por ácido.
