Path (1) is not possible in, for example, atactic polymers lacking a crystalline ordering state. (b) Temperature dependence of the isobaric expansivity (also called coefficient of thermal expansion) [a = V -1 (0 VIOT)P], heat capacity [ C p = (HOT)P], and log 10 of viscosity (n ), in the region of Tg
