Abstract

The dispersions are produced with a relatively high content of a solubilised polymeric material which serves in the presence of paper filler as binder and dissolves only with difficulty, by continuously passing an aqueous suspension of the particulate binder through a treatment zone (2,3,4) in at least part of which it is subjected to shear, the rate of flow and degree of shear being such that the residence time in the zone allows optimum swelling of the binder and the resulting solution of polymeric binder is visually homogeneous. Flocculant and filler are preferably also incorporated to provide a continuous supply of preflocculated filler for a papermaking furnish. Typical materials are cold water soluble starch as binder, polyacrylamide as flocculant and chalk whiting as filler. <IMAGE>
