Polymer Chemistry: Transitions

Transition regions are narrow temperature intervals over which the properties of a polymer change by a large amount. The most important examples are the glass transition and the crystal melting transition. Most semicrystalline polymers exhibit their most useful properties between the temperatures of the glass transition, Tg, and the crystal melting point, Tm
