Abstract
é descrito um copolímero contendo cátion multivalente derivado a partir de um ou mais ácidos etilenicamente insaturados. o copolímero tem as seguintes características: (a) uma viscosidade intrínseca de pelo menos cerca de 3 dl/g quando medida em 1 m de solução de nacl a 25°c; (b) o copolímero é derivado de uma mistura de monômero compreendendo um ácido etilenicamente insaturado e pelo menos um comonômero, o ácido etilenicamente insaturado presente em uma quantidade na faixa de a partir de cerca de % a cerca de 65% em peso; e (c) um teor de comonômero residual é menos que 1000 ppm quando o comonômero é uma acrilamida. o copolímero, inter alia, é útil como um floculante para tratar uma pasta fluida aquosa compreendendo material particulado, preferivelmente rejeitos de uma operação de mineração.
