Abstract
A polymer has a repeating unit including at least one alkynyl group, at least one borate group, at least one silyl group and/or at least one siloxyl group. The polymer may be prepared by reacting a first compound having at least one alkynyl group and at least one siloxyl group and a second compound selected from boric acid, hydrocarbon borate, hydrocarbon boronic acid, and pyroboric acid. The polymer of the present invention possesses both the processability of an organic polymer and the thermal and oxidative stability of an inorganic polymer.
Claims20
