PURPOSE: To enable an arbitrary water-insoluble high-molecular branched polymer to be obtained from a diallylic quat. ammonium salt by using a diallyl isocyanurate salt.
CONSTITUTION: Diallyl isocyanurate is neutralized with an aq. soln. of a metal hydroxide to obtain a water-soluble vinyl monomer crosslinking agent which is a diallyl isocyanurate salt of the formula (wherein M is a monovalent metal). 0.1-100mol% crosslinking agent is added to a water-soluble vinyl monomer having a solubility of at least 1.5wt.% in water (20°C) and selected from among diallylic quat. ammonium salts, (meth)acrylic acid, (meth)acrylic esters, (meth) acrylamide, and vinylpyrrolidone, and the monomer is polymerized in the presence of a polymn. initiator to obtain a water-insoluble high-molecular three- dimensional polymer.
