Abstract
<B>''MICROGéIS DE POLISSILICATOS''<D>. A presente invenção, de um modo geral, se refere a microgéis de polissilicatos. Mais especificamente, a invenção se refere a um processo para preparação de microgéis de polissilicatos aquosos, que compreende misturar uma solução aquosa de silicato de metal alcalino com uma fase aquosa de um material à base de sílica, tendo um pH de 11 ou menos, ou a microgéis de polissilicatos per si e uso dos mesmos como agentes de floculação na fabricação de papel e na purificação de água. A invenção ainda se refere a um processo para produção de papel a partir de uma suspensão de fibras celulósicas e carga opcional, que compreende adicionar à suspensão pelo menos um polímero orgânico catiónico ou anfótero e um microgel de polissilicato, formando e drenando a suspensão sobre uma tela de arame.
