Abstract
PURPOSE: To produce titled synthetic membrane useful as a permeable membrane or the like, by emulsion-polymerizing a vinyl monomer in the presence of a water- soluble polymer and a redox initiator system containing H2O2 as an oxidizing agent and extracting the linearly polymerized hydrophobic polymer particles with a solvent.
CONSTITUTION: A porous synthetic membrane of an OH-containing, water-soluble or hydrophilic polymer, having uniform passages and an extremely large surface area is prepared by emulsion-polymerizing, while preventing graft-polymerization, a vinyl monomer which provides a hydrophobic polymer 12, such as vinyl acetate, in an aqueous medium containing a water-soluble polymer 10 such as PVA, by use of a redux polymerization initiator containing hydrogen peroxide as an oxidizing agent, thereby to form a linear polymer (this polymer forms ultimately a membranous product in which the hydrophobic polymer particles are arranged in the state of the closest packing), and extracting the hydrophobic component only with a solvent such as acetone thereby to form pores 18. This membrane is useful as a permeable membrane, adsorbing membrane, exchanging membrane or membrane for catalytic reaction.
