Abstract
A process for the preparation of resin particles comprising: adding a mixture of at least one free radical reactive monomer continuously to a heated aqueous solution of a water soluble free radical initiator and a water soluble salt to form latex emulsion particles and aggregates thereof; and wherein the rate of continuous addition of said monomer is greater than the rate at which monomer is consumed by polymerization.
Claims3
