Provided are polymers comprising the condensation product of silicon-containing reactants. Also provided are compositions suitable for use in forming optical waveguides which include such polymers, as well as optical waveguides formed from such polymers. The polymers, compositions and optical waveguides have particular use in the formation of printed wiring boards having electrical and optical functionality.

Silicon-containing polymers and polymers and optical waveguides formed therefrom

Provided are compositions suitable for use in forming a flexible optical waveguide. The compositions include a polymer, having units of the formula (RSiO), wherein R is a substituted or unsubstituted organic group, and a plurality of functional end groups. A first component is provided for altering the solubility of the composition in a dried state upon activation. A second component contains a plurality of functional groups chosen from hydroxy, amino, thiol, sulphonate ester, carboxylate ester, silyl ester, anhydride, aziridine, methylolmethyl, silyl ether, and combinations thereof. The second component is present in an effective amount to improve flexibility of the composition in a dried state before and after activation. Also provided are flexible optical waveguides, methods of forming flexible optical waveguides and electronic devices that include a flexible optical waveguide.
