发明名称 Method of using poly(vinyl alcohol) fluidized polymer suspensions in aqueous systems
摘要 At least 20% of poly(vinyl alcohol) (PVA) is dispersed in an aqueous solution of at least one salt dissolved therein selected from the group of sodium or potassium formate, sodium, potassium, or magnesium sulfate, sodium or potassium citrate, sodium or potassium polyacrylate, or mixtures thereof. This aqueous suspension of PVA is useful in systems in which PVA is dissolved in order to reduce the time of dissolution.
