Patent

CA 2626380

A silicon composition comprising a copolymer is provided. The copolymer has the formula H - [SiH2CH2]xn[Si(R1)HCH2]yn[SiH(R2)CH2]zn - H wherein R1 is methyl, phenyl, methoxy, ethoxy, or butoxy; wherein R2 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.

Composition de silicium qui contient un copolymère de formule H - [SiH2CH2]xn[Si(R1)HCH2]yn[SiH(R2)CH2]zn - H dans laquelle R1 représente méthyle, phényle, méthoxy, éthoxy ou butoxy, R2 représente allyle, propargyle ou éthynyle et x + y + z = 1 à condition que x, y et z ne soient pas égaux à 0. La présente invention concerne également des procédés de production de matériaux à base de carbure de silicium contenant le copolymère susmentionné et des articles produits à l'aide desdits matériaux.
