The Glass Transition of Polymers
The glass transition is not limited to special types of materials. Every class of material can be tansformed in an armorphous solid (without crystallinity) if the experimental parameters are adjusted to the dynamics of the system. Consider therefore two extreme examples. Consider the system consisting of spherical molecules such as rare gases. The hopping time of the spheres is very short and the dynamics extremely fast.
