Abstract
Patente de Invenção: <B>"USO DE PRODUTOS DE AMIDO MODIFICADOS COMO AGENTE DE RETENçãO NA PRODUçãO DE PAPEL"<D>. A invenção refere-se ao uso de amidos modificados como agente de retenção para pigmentos, cargas inorgânicas e finos em fabricação de papel. Os ditos amidos modificados são obtidos por decomposição de amido, de derivados do amido e/ou de produtos de ruptura dos mesmos em solução aquosa na presença de pelo menos um polímero catiónico constituído de pelo menos 20% em peso de unidades amida do ácido dialquilaminoalquil (met) acrílico e de pelo menos uma substância mineral inorgânica.
