Abstract
An organometallic polymer material having a -M-O-M- bond (M is a metal atom) and containing a metal alkoxide having only one hydrolyzable group and/or a hydrolysate of the metal alkoxide and preferably further containing an organic acid anhydride and/or an organic acid.
Claims21
An organometallic polymer material having a -M-OM- bond (M is a metal atom), containing:
- a metal alkoxide having only one hydrolyzable group and/or a hydrolysate of said metal alkoxide;
- and
- an organic acid anhydride and/or an organic acid,
- wherein said metal alkoxide or said hydrolysate is contained in the state where it is not bound to the organometallic polymer,
- each light propagation loss in wavelength ranges of 500 to 1100 nm, 1300 to 1350 nm and 1450 to 1550 nm is 15 dB/cm or smaller, and
- at least one kind of particle composed of a material having a refractive index different from that of said organometallic polymer is contained in said organometallic polymer.
