| 摘要 |
A thermoset polymer has a repeating unit comprising at least one crosslinking group having at least one unsaturated carbon-carbon bond and at least two crosslinking bonds, at least one borate group, at least one silyl group and/or at least one siloxyl group. The thermoset polymer of the present invention may be prepared by reacting a first compound having at least one alkynyl group, and at least one group selected from silyl groups and siloxyl groups, with a second compound selected from boric acid, hydrocarbon boronic acid, hydrocarbon borate, and pyroboric acid under reaction conditions sufficient to crosslink a sufficient number of alkyne bonds to form the thermoset polymer. The thermoset polymer of the present invention possesses both the processability of an organic polymer and the thermal and oxidative stability of an inorganic polymer. The thermoset polymer of the present invention may be further processed into a ceramic material by pyrolysis.
