| titleOfInvention | Colloidally stable dispersions |
| abstract | ABSTRACT Ionic interfacially spreading polyelectrolytes used to stabilize dispersions are prepared from a hydro-phobic interpolymer containing reactive units which can later be converted to ionic units. More particularly, this invention provides a dispersion containing a stabil-izing amount of a substantially non-copolymerizable linear interpolymeric interfacially spreading polyelectrolyte in both the disperse and continuous phase of said dispersion wherein: (1) said polyelectrolyte is composed of a mixture of nonionic hydrophobic units and ionic hydrophilic units and wherein said nonionic hydrophobic units are randomly distributed in the backbone of said polyelectrolyte, (2) said polyelectrolyte is adsorbed at said disperse phase in a substantially flat configuration and where the area occupied by each ionic hydrophilic unit of said polyelectrolyte at the disperse phase surface is from about 60 to 100 square Angstrom units per hydrophilic unit, and (3) said poly-electrolyte has an adsorption constant equal to or greater than 1 at the point where the disperse phase is saturated with said polyelectrolyte wherein said adsorption constant is determined as the amount of polyelectrolyte in said disperse phase divided by the amount of polyelectrolyte in said continuous phase characterized in that the poly-electrolyte stabilizing the dispersion has been made by homogeneous copolymerization of nonionic functional monomers and thereafter converting at least some of the functional groups to ionic groups. |
