摘要
Bis(β-alkoxy-ethyl cyclopentadienyl) titanium (zirconium) dichlorides was newly synthe-sized,and through interfacial polycondensation of bis(β-alkoxy-ethyl cyclopentadienyl) titanium dichlorides with diacids,diphenols,and hydroxy-acids,a series of new titanium polymers were prepared.The polymers obtained are yellow in color,having mol. wts between 10^3-10^6.They possess heat-resistant properties and show better solubilities that Carraher′s series.Thus,TG/DTG determinations showed that while suffering initial loss of wts. at around 260℃-470℃,they remain stable at 600-800℃.Residual wts.are around 50% of the initial at 947.5℃.They are soluble in glacial acetic acid,DMAC,DMF,and DMSO.
