WebThe glass transition temperature is calculated using a half-height technique, which means identifying the midpoint of the “kink” or the middle of the sloped region. To understand … Web15 apr. 2013 · Glass Transition Temperature (referred herein as Tg) is the point at which a material goes from a hard brittle state to a soft rubbery state. Amorphous polymers only have a Tg. Crystalline polymers exhibit a Tm (melt temperature) and typically a Tg since there is usually an amorphous portion as well ("semi"-crystalline).
