ABSTRACT:
This invention is directed to dispersions containing stabilizing amounts of certain substantially linear interpolymeric interfacially spreading polyelectrolytes composed of a mixture of nonionic hydrophobic units and ionic hydrophilic units where the nonionic units are randomly distributed in the backbone of the polyelectrolyte and where the polyelectrolyte is adsorbed at the surface of the disperse phase of the dispersion in a substantially flat configuration. The polyelectrolytes are further characterized by having an adsorption constant equal to or greater than 1 at the point where the surface of the disperse phase is saturated with the polyelectrolyte, the absorption constant being determined as the amount of polyelectrolyte in the disperse phase divided by the amount of polyelectrolyte in the continuous phase. These stabilized dispersions are particularly useful as coating compositions and for use in the preparation of microspheres and seed latexes.
