Method of forming polymer particles

摘要

A process for forming polymeric particles from water-soluble polymers by introducing the polymer into an aqueous salt solution in which the salt is of a composition and present in an amount sufficient to inhibit solubilization of the polymer therein and subsequently introducing into the aqueous medium a multifunctional reagent and mixing said aqueous medium for a time and at a temperature sufficient to cause reaction between the polymer and the reagent. The resultant solid polymer is readily recovered.
