| titleOfInvention | The synthetic method of high ceramic yield Polycarbosilane |
| abstract | The invention discloses a kind of synthetic method of high ceramic yield Polycarbosilane, molecular weight is pressed 100 in 500 1500 Polycarbosilane and allyl compound:(12~4) after mixing; it is dissolved in dimethylbenzene; it is placed in reaction vessel, adds organolithium reagent, heats up and reacted under protective gas protection; it is 100~150 DEG C to control maximum temperature; and insulation reaction 2~8 hours, after reaction terminates, it is filtered to remove insoluble matter; solvent is evaporated off, high ceramic yield Polycarbosilane is obtained.The present invention has that reaction condition is easily controllable, method is easy, and product has self-crosslinking ability, and the characteristics of Si H and adjustable allyl content, can conveniently prepare liquid or the high ceramic yield Polycarbosilane of solid-state. |
