Abstract

PURPOSE: To prepare a water-in-oil type polymer emulsion useful as a flocculant for water treatment, etc. and containing a reduced amount of the residual monomer, by polymerizing a specific amount of a water-soluble vinyl monomer in the presence of a surface active agent, an organic liquid and an oil-soluble polymerization initiator, and thereafter carrying out the polymerization in the presence of a water- soluble polymerization initiator.
CONSTITUTION: A water-soluble vinyl monomer (e.g. acrylamide, etc.) dissolved in water is emulsified in a hydrophobic organic liquid (e.g. isoparaffin etc.) containing a surface active agent (e.g. polyoxyethylene sorbitol monooleate etc.). An oil-soluble polymerization initiator [e.g. azobis(dimethylvaleronitrile) etc.] as a radical-generating polymerization initiator is incorporated to the emulsion and ≥50% of the monomer is polymerized. Thereafter the residual monomer is polymerized in the presence of a water-soluble polymerization initiator [e.g. azobis (sodium cyanovalerate), etc.].
