摘要：

The reaction of di-t-butoxysilanediol with bis(acetylacetonato)titanium di-iso-propoxide gave cyclic titanosiloxane. Silicon tetraacetate was reacted with boron tri-n-butoxide in THF to form polyborosiloxanes with molecular weight around one thousand. Monolithic SiO2B2O3 gels were obtained on aging a solution of the reaction product. High molecular weight polyborosiloxanes, capable of forming gel fibers, were obtained by the reaction followed by partial alkoxylation and subsequent hydrolysis. The hydrolysis of bis(ethyl acetoacetato)zirconium diethoxide was investigated to obtain polyzirconoxanes as a precursor for the oxide materials. The product was found to be a low molecular weight polymer formed by condensation of the partial hydrolysis product which showed good spinnability and gave gel fibers. © 1990.
