Abstract
A process for the preparation of carrier powder polymer coatings which comprises the supercritical polymerization of a monomer and surfactant in a supercritical medium to form a porous polymer, and thereafter adding thereto a second polymer, and which second polymer is incorporated into the porous polymer.
Claims15
A process for the preparation of coated carrier particles containing a carrier core coated a polymer containing thereover a surfactant and which process consists essentially of admixing a carrier core with a monomer, and effecting supercritical polymerization of said monomer in a supercritical medium;
- and thereafter adding thereto a second polymer.
