Abstract

"PROCESSO CONTìNUO PARA PREPARAçãO DE MICROGéIS DE POLISSILICATO". A presente invenção se refere a um processo contínuo para a preparação de microgéis de sílica através da utilização de dióxido de carbono como iniciador em gel sob pressão de pelo menos cerca de 172 kPa (cerca de 25 psig). Pode-se produzir desempenho consistente de microgel com taxas de produção variáveis.
