On cooling, a molten polymer may undergo either crystallisation (route a) or a transition into a glass (i.e. a frozen, amorphous liquid) according to route b. These two possibilities are displayed in the specific volume-temperature diagram of Fig. 5.1. The glass transition involves a change in the slope in the specific volume temperature plot (route b).

摘要

On cooling, a molten polymer may undergo either crystallisation (route a) or a transition into a glass (i.e. a frozen, amorphous liquid) according to route b. These two possibilities are displayed in the specific volume-temperature diagram of Fig. 5.1. The glass transition involves a change in the slope in the specific volume temperature plot (route b).
