Abstract

An improvement in a papermaking process in which an aqueous paper furnish containing cellulosic pulp, and optionally also mineral fillers is formed and dried, the improvement being the addition of a drainage and retention aid comprising a water soluble alkali metal polyaluminosilicate microgels formed from the reaction of polysilicic acid and an alkali metal aluminate, the polyaluminosilicate having an alumina/silica mole ratio greater than about 1/100, together with a cationic polymer selected from the group consisting of cationic starch, cationic guar and cationic polyacrylamide.
