OLIGOMER FOR BACTERIUM IMMOBILIZATION CARRIER, HYDROUS GEL OF THE OLIGOMER POLYMERIZATION AND HYDROUS GEL OF THE OLIGOMER POLYMERIZATION WITH IMMOBILIZED BACTERIUM

摘要

PROBLEM TO BE SOLVED: To obtain an oligomer for a bacterium immobilization carrier capable of greatly increasing the retention of a bacterium, neither changeable in qualities nor decomposable with a bacterium, having a high mechanical strength and harmless to natural environment. SOLUTION: This oligomer for the bacterium immobilization carrier is provided with a subsidiary skeleton part composed of a urethane bond and ethyleneoxy or a urethane bond, ethyleneoxy and propyleneoxy between a main skeleton part of a polyalkylene glycol and polymerizable double bonds located at both ends of the main skeleton part to lengthen a main chain and increases strength and abrasion resistance besides flexibility by network formation through the urethane bond. On the other hand, in order to alleviate hydrophobicity of a urethane part, the ethyleneoxy is bonded to the subsidiary part to improve compatibility with a bacterium.
