Physical studies of ionically-terminated polytetrahydrofuran polymers. I. Dilute solution behavior

A series of tetrahydrofuran polymers, terminating at one end with a pyridinium bromide group, were prepared; their hydrodynamic behavior contrasted with the equivalent methoxyterminated polytetrahydrofurans. This article reports viscometry studies of these polytetrahydrofurans in cyclohexane, toluene, tetrahydrofuran, methyl ethyl ketone, and cyclohexanone.
