Glass Transition Temperatures of Polytriazole Resins

1 The Effect of Molecular Rigidity and Polarity on the Glass Transition Temperature (T ) 

The glass transition temperatures of AjB j resins (m = 1,2,3.7) with different chain lengths between two crosslinking sites are 

In general, the increasement of crosslinking density of a network would result in enhancement of thermal properties. We consider the molecular weight of two adjacent crosslinking sites as a cross-linking density. Based on the theory of glass transition, can often 

Resin A3B, A3BV A3BV A3BV A3BV A,BV A,BV A3BV 

From the results front, we can conclude that the size of the network grids has an effective influence on T s of polytriazoles small network grids of polytriazoles would result in a high T.
