Question

what does the effect of glass transition temperature on the polymer properties? Explain that?

Answer 1

Answer:

The glass transition temperature (Tg) is the temperature of amorphous polymers at which increased molecular mobility results in significant changes in the thermal properties.

Answer 2

Answer:

Polymers. In polymers the glass transition temperature, Tg, is often expressed as the temperature at which the Gibbs free energy is such that the activation energy for the cooperative movement of 50 or so elements of the polymer is exceeded. This allows molecular chains to slide past each other when a force is applied.
