Abstract
Provided are an immobilization carrier, a polyether compound used for production thereof and a method for producing the carrier. The immobilization carrier have both excellent strength and toughness while a content of a polymer forming hydrous gel is suppressed, The immobilization carrier includes a polymer having a repeated unit provided with a bisphenol group and a polyoxyalkylene group bonded to the bisphenol group. The polyoxyalkylene group is formed via copolymerization between an oxyethylene group and an oxyalkylene group with 3 or more carbon atoms and optionally having a substituent. A method for producing the immobilization carrier includes the step of preparing hydrous gel via polymerizing a polyether compound in an aqueous solution. The polyether compound includes a bisphenol group, a polyoxyalkylene group and a polymerizable group. The immobilization carrier may be applied to a microorganism immobilization carrier used for treating wastewater.
