    摘要： A bead-like glycidyl (meth)acrylate polymer is produced by aqueous suspension polymerization of glycidyl (meth)acrylate alone or a monomer mixture composed of more than 50 weight % of said monomer and at least one other monomer which forms the remainder, in the presence of a specific aqueous polymer, at a pH of from 2 to 9 and at a stirring speed of from 50 to 500 r.p.m. By heat treating said bead-like polymer at a pH below 3 and at a temperature above 70.degree. C., hydroxyl groups resulting from the ring opening of the epoxy groups are introduced, whereby a solvent-insoluble bead-like polymer having a gel water content not less than 30% is produced.

    摘要： The present invention provides a gel having excellent separation ability, operability and a long life, for separating useful components from a rhodanate-containing detoxication treated liquid. The gel consists of a cross-linked polymer with more than 50 weight % of repeating units which are composed of 2,3-dioxypropyl (meth)acrylate or 2,3-dioxypropyl (meth)allyl ether, and whose average particle diameter is more than 10.mu. and gel water content is from 30 to 150%. The present invention also provides a method of separation using said gel.
