Unit 3- Class 10- High Polymers (Glass transition temperature (importance of glass transition temperature))

Importance of Tg:

1.    Tg value is a measure of flexibility of a polymer.
2.    Tg gives us idea of the thermal expansion, heat capacity, electrical and mechanical properties of the polymer.
3.    The use of any polymer at any temperature is decided by its Tg value.
4.    Knowledge of Tg is useful in choosing appropriate temperature range for such processing operations. 

Well this is it about glass transition temperature. Next we will learn about Structure property relationship of polymers.
