N—H free and SI-rich per-hydridopolysilzane compositions, their synthesis, and applications

A method of synthesizing a N—H free, C-free, and Si-rich perhydropolysilazane composition, the method comprising mixing trisilylamine and a catalyst to produce the N—H free, C-free, and Si-rich perhydropolysilazane composition having a molecular weight ranging from approximately 332 dalton to approximately 100,000 dalton, further comprising mixing trisilylamine and the catalyst at room temperature and atmospheric pressure.

A method of synthesizing a N—H free, C-free, and Si-rich perhydropolysilazane composition, the method comprising mixing trisilylamine and a catalyst to produce the N—H free, C-free, and Si-rich perhydropolysilazane composition having a molecular weight ranging from approximately 332 dalton to approximately 100,000 dalton, wherein the catalyst is B(C6F5)3, further comprising adding a quenching agent when a N—H free, C-free, and Si-rich perhydropolysilazane composition obtains the desired molecular weight.
