Abstract

Se proveen dispersiones acuosas de polímeros cationicos solubles en agua, así como también procesos para prepararlas y métodos para usarlas. Lospolímeros cationicos contienen unidades recurrentes en cantidades que fomentan la formacion de la dispersion acuosa y/o ventajosamente reducen la viscosidadvolumétrica de la dispersion acuosa.
