Abstract

"PROCESSO PARA O FRACIONAMENTO DE DISPERSõES DE POLìMEROS". Esta invenção refere-se a um processo para o fracionamento de composições de reação do polímero. O processo reduz o gel na composição de reação do polímero através de ajuste do pH do polímero para 7 a 11 anterior ao fracionamento e manutenção do pH ajustado durante o fracionamento, mantendo-se a temperatura do polímero em 30°C a 70°C durante o fracionamento, utilizando uma operação de fracionamento contínua, ou suas combinações.
