UN METODO DE POLIMERIZAR MONOMEROS HIDROSOLUBLES EN SUSPEN- SION DE AGUA EN ACEITE ESTILIZANDO UN AGENTE DE SUSPENSION AMINADO MEJORADO.

摘要

This invention is a method for water-in-oil suspension polymerization for making polymers of water-soluble ethylenically unsaturated monomers. This method comprises (1) forming a water-in-oil suspension of an aqueous solution containing a water-soluble ethylenically unsaturated monomer dispersed in an inert hydrophobic organic liquid containing an aminated inorganic suspending agent having a low hydrophile-lyophile balance and (2) heat polymerizing the suspended monomer in the presence of a catalytic amount of a polymerization initiator to form a water-in-oil suspension of polymeric product. The method is characterized in that the suspending agent is substantially free of unreacted aminating agent.
