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).
