PROBLEM TO BE SOLVED: To provide a new trisoxetane ether compound preparing a polymer having excellent thick membrane-forming properties, curability, heat resistance, etc., to provide a method for producing the compound and to provide an optical waveguide using the compound. SOLUTION: Specific phenols are converted into a cesium phenolate with a cesium salt and then reacted with a sulfonic ester of a 3-alkyl-hydroxymethyloxetane. Thereby, the trisoxetane ether compound is produced. The optical waveguide is equipped with a substrate 1 and a clad layer 2 formed on the substrate 1 and a core part 3 propagating an optical signal is formed in a prescribed pattern in the clad layer 2. At least one of the clad layer 2 and the core part 3 is formed of a resin composition comprising the trisoxetane ether compound. COPYRIGHT: (C)2007,JPO&INPIT |
