Abstract:

The glass transition temperatures of an inorganic anionic phosphate polymer system was studied over a wide range of counterions. It was shown that the glass transition temperature could be varied between -10C to 520C, and that a plot of the glass Transition Temperature versus the ratio of the cation change g to internuclear distance between the cation and the oxygen on the polymer backbone a yielded a straight line over the entire temperature range a theoretical justification for this linearity was presented. It was further shown that the increase in the glass transition with ga is due not only to an increase in the interchain forces, but also to an increase in the carrier to internal rotation between neighboring groups.
