ABSTRACT:
The binary suspension polymerization of a water soluble monomer and an organophilic or hydrophobic monomer having a low Tg in an integrated aqueous suspension system wherein the suspension medium for said organophilic monomer droplets comprises a hydrophilic monomer having a higher rate of reaction than the hydrophobic monomer and water in a mixture such that a solution of between about 1,000 and about 100,000 cps Brookfield viscosity is maintained in the reaction zone during polymerization of the organophilic droplets.
