ULTRAVIOLET SPECTROPHOTOMETRIC DETERMINATION OF ISOTRUXENE IN AUTOCLAVE-PRODUCED INDENE POLYMERS

摘要

A spectrophotometric method has been developed for determining the content of isotruxene in truxene-isotruxene mixtures produced by the autoclave poly¬merization of indene. The accuracy of the method is not precisely known due to the uncertainty of the impurity level in the isotruxene standard;however, it is estimated to be ± 3.4 percent absolute assuming the purity of the isotruxene is 97 ± 2 percent absolute.
