Effect of Temperature on Polymers: Solids on heating eventually melt to form a liquid. With polymers it is not so simple rubber on cooling (in liquid nitrogen) becomes brittle or glassy. Many polymers have a mixture of ordered (crystalline) regions and random (amorphous) regions. In the glassy state‚ the tangled chains in the amorphous region are frozen so movement of chains is not possible the polymer is brittle. If the glassy material is heated‚ the chains reach a temperature at which they
