| titleOfInvention | High spinnability Polycarbosilane and preparation method thereof |
| abstract | The present invention relates to high spinnability Polycarbosilanes and preparation method thereof, which comprises by benzyl magnesium chloride and chloromethyl chlorosilane mixes and grind into powder；Supercritical fluid recrystallization method is used again, obtains powder of uniform size；Powder is mixed with magnesium powder, tetrahydrofuran, then uses grignard coupling method, synthesis is containing benzyl chloride for liquid hyperbranched polycarbosilanes；Liquid hyperbranched polycarbosilanes are obtained for liquid hyperbranched polycarbosilanes containing benzyl chloride with lithium aluminium hydride reduction；It places it in distilling apparatus, air-distillation simultaneously collects the fraction at a temperature of 400 DEG C~500 DEG C, as pure Polycarbosilane.The preparation method of high spinnability Polycarbosilane of the invention, the hyperbranched Polycarbosilane being prepared is coupled using grignard, with excellent mobility, simultaneously because using benzyl magnesium chloride as raw material, the degree of branching of Polycarbosilane is reduced to a certain extent, make product that there is better linear structure, and mobility is high, spinning property also significantly improves. |
