Procedure

A 250 ml, three-necked round-bottom flask was sparged with nitrogen and equipped with a 50 ml dropping funnel, a thermometer, a stir bar, and a septum. The flask was charged with 38.38 ml (38.38 mmol) BH3.THF adduct and cooled to 0° C. in an ice bath. The dropping funnel was charged with 7.78 ml (76.7 mmol) cyclohexene and 36 ml tetrahydrofuran (THF). The cyclohexene/THF mixture was added dropwise over 45 min. A white solid (dicyclohexylborane) formed. The reaction mixture was stirred for one hour at 0° C. The dropping funnel was then charged with 13.0 g (202.0 mmol) poly(methylvinyl)silazane, [(MeSiHNH)0.8 (MeSiViNH)0.2 ]x and 36 ml THF and added to the reaction mixture over 30 min. After the polysilazane addition was complete, the reaction mixture was stirred for 30 min at 0° C. and then warmed to room temperature. The white solid disappeared and a clear solution was formed. The boron-substituted polysilazane, Polymer III, contained about 2.1 wt % boron bound to the polymer backbone. This solution was used in the following example.
