WebNov 1, 2024 · Glass Transition Temperature. When an amorphous polymer is heated, the temperature at which it changes from a glass to the rubbery form is called the glass transition temperature, T g. A given polymer sample does not have a unique value of T g because the glass phase is not at equilibrium. The measured value of T g will depend on …
