Abstract

Patente de Invenção: <B>"PROCESSO PARA A PREPARAçãO DE POLìMEROS HIDROSSOLúVEIS OU INTUMESCìVEIS NA áGUA COM TEOR DE MONÈMEROS RESTANTES MUITO BAIXO, PRODUTOS PREPARADOS PELO MESMO E SEU EMPREGO"<D>. A invenção refere-se a um processo para a preparação de polímeros hidrossolúveis ou intumescíveis na água de ácido acrílico e/ou derivados de ácido acrílico parcial ou totalmente neutralizados com compostos de nitrógenio com teores muito baixos de monómeros restantes, que é caracterizado por um aquecimento posterior do polímero em temperaturas de 120 até 240°C. Os polímeros preparados pelo mesmo prestam-se entre outros para a aplicação como agentes de floculação, agentes de dispersão e absorventes.
