Crystalline amorphous
WebTg depends on the chemical structure of the polymer defined by its crystallinity. They may be amorphous, crystalline or semi-crystalline. Amorphous-polymers Amorphous polymers have a random molecular structure. At Tg, they take the glassy-state properties like brittleness, stiffness, and rigidity (upon cooling). WebMetals and ionic compounds typically form ordered, crystalline solids. Substances that consist of large molecules, or a mixture of molecules whose movements are more …
