ABSTRACT:
(1) A method for making a water soluble synthetic solid polymer product, which method comprises polymerizing a solution of a water soluble monomer, or of a mixture of monomers which are exclusively or predominantly water soluble monomers, in an aqueous medium in the presence of 0.5 to 50 percent, by weight of said monomer or monomers, of at least one member selected from the group consisting of water soluble solid monosaccharides and oligosaccharides, and (2) the directly millable polymer product having a low degree of crosslinking which is prepared thereby and which is useful as a flocculant, dispersing agent, thickening agent, water treating agent, coating agent or the like.
