ABSTRACT:
Disclosed is an improved process for affecting preparation of resin particles by a bead polymerization reaction which for example comprises (1) providing a solution mixture of water, suspension agent, and surfactant; (2) adding thereto while stirring a monomer component, a low molecular weight wax, and a polymerization initiator; (3) affecting polymerization of the monomer by heating the resulting solution at a temperature of from about 90 degrees Centigrade to about 120 degrees Centigrade; and (4) separating the resulting polymer from the reaction mixture.
