Question & Answer
Choose the Best Answer
It improves both thermal stability and allows for higher processing temperatures.
It decreases thermal stability and requires lower processing temperatures.
It has no effect on thermal stability but lowers the processing temperature.
It increases brittleness, negatively impacting processing conditions.
Understanding the Answer
Let's break down why this is correct
Increasing Tg means the polymer stays firm for longer. Other options are incorrect because Many think a higher Tg hurts stability, but it is the opposite; Some believe that a higher Tg means you must lower the temperature to process.

Definition
Polymer Glass Transition Temperature (Tg) is the temperature at which a polymer transitions from a rigid, glassy state to a flexible, rubbery state. Understanding Tg is crucial as it determines a polymer's properties like flexibility and brittleness, impacting real-world applications such as the Challenger shuttle disaster.
