Ebulliometric studies on the hydrolysis of tantalum pentaalkoxides Ta(OR) 5 , where R = Me, Pr n , Bu n , and Bu s , have furnished important data on the polymeric nature of tantalum oxide alkoxides. It is shown from the variation of number-average degrees of polymerization as a function of degree of hydrolysis that the polymers conform to certain structural models. The structural models involve 6-co-ordinated tantalum.
