| 摘要 |
This invention provides a process for the production of molded particles for enzyme- or microbial cell-immobilization which is characterized in that:an aqueous liquid composition which comprises:(A) an unsaturated group-containing urethane resin which is obtained by making a compound (a) having one hydroxyl group and one epoxy group in a molecule react with a compound (b) having one carboxyl group and one ethylenically unsaturated group in a molecule, and further making thus obtained unsaturated group-containing diol (c) react with polyisocyanate compound (d);(B) a polymerization initiator; and(C) water-soluble macromolecular polysaccharides which are capable of gelation by contact with metal ion;is gelatinized, in an aqueous medium which contains metal ion, to be particulate gel, which is then subjected to photopolymerization and/or thermopolymerization by which to cause the crosslinking reaction of ethylenically unsaturated group in said particulate gel.
