Abstract

"PROCESSO PARA A PRODUçãO DE POLìMEROS, POLìMERO CONTENDO UNIDADES DE ACRILATO DE SóDIO, E, USO DE ACRILATO DE SóDIO SóLIDO". Processo para a produção de polímeros, que contêm unidades de acrilato de sódio, através de polimerização por adição de radical livre de acrilato de sódio e, se requerido, de outros monómeros em meio aquoso, em que é usada uma solução aquosa de acrilato de sódio, que é obtida através da dissolução ou dispersão de acrilato de sódio sólido em um meio aquoso. Os polímeros assim obtidos apresentam um índice de cor aperfeiçoado e um conteúdo de monómeros residuais mais baixo em relação a polímeros comparáveis convencionais.
