PROBLEM TO BE SOLVED: To produce a corsslinked polymer in such a manner as to perform a seed crystal/feedstock method very easily without forming coagulation by using a microcapsule-enclosed polymer as seed crystal. SOLUTION: When a crosslinked polymer is produced by a seed crystal/ feedstock method, a microcapsule enclosed crosslinked polymer is used as the seed crystal to be used. Further, as the crosslinked polymer, e.g. a polymer which is prepared by polymerizing a polymerizable ethylenic unsaturated monomer with a crosslinking agent is used. Here, it is preferable that the monomer is styrene, etc., the crosslinking agent is divinylbenzene, etc., and the polymer is bead-shaped polymer, etc. |
