Process for the production of molded particles for microbial cell-immobilization |
摘要 |
This invention provides a process for the production of molded particles for microbial cell-immobilization which is characterized in that: an aqueous liquid composition which comprises: (a) an ethylenically unsaturated group-containing urethane resin which is obtained by making a tertiary amino group-containing diol react with a polyisocyanate compound, and by further introducing an ethylenically unsaturated group; (b) a polymerization initiator; and (c) water-soluble macromolecular polysaccharides; 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.
