Abstract

The invention provides a process for preparing a water dispersed polymer blend, comprising the steps of: PA1 (I) mixing PA2 (a) water; PA2 (b) at least one ethylenically unsaturated monomer; PA2 (c) at least one branched water-dispersible sulfopolymer; and PA1 (II) polymerizing the ethylenically unsaturated monomer within the mixture to provide the water dispersed polymer blend.
