| abstract |
A silicon composition comprising a copolymer is provided. The copolymer has the formula H—[SiH 2 CH 2 ] xn [Si(R 1 )HCH 2 ] yn [SiH(R 2 )CH 2 ] zn —H wherein R 1 is methyl, phenyl, methoxy, ethoxy, or butoxy; wherein R 2 is allyl, propargyl, or ethynyl; and wherein x+y+z=1 with the proviso that x, y, and z are not 0. Methods for making silicon carbide based materials using the aforementioned copolymer and articles made thereby are also provided. |
