摘要：

Benzyloxy-terminated poly(1,3,6-trioxocane)s are separated into oligomers by supercritical fluid chromatography. Depending on the chemical structure of the polytrioxocane. two to three peaks are obtained for each degree of polymerization, corresponding to different types of functionality. Up to a degree of polymerization of n = 7 the alpha,omega-dihydroxy, alpha-hydroxy-omega-benzyloxy and alpha,omega-dibenzyloxy species are well separated.
