Abstract

Binders dissolved in water, which contain a mixture of a high molecular-weight polymer, solvated by carboxylate groups, of an ethylenically unsaturated carboxylic acid polymerisable by a free-radical mechanism and of dissolved native starch, are almost completely precipitated if an acidifying agent is gradually added until coacervation and precipitation of the binder occur. In the manufacture of highly filled papers, the pigment can be bound in this way from an aqueous suspension.
