Does that mean that a (non-crystalline) polymer at a temp. beneath the
Tg is a fluid as well? I have not seen a definition that I have been
happy with, but all that I do see imply that a fluid is a state of
matter that is not rigid. I have always used the term "glass" to
describe various materials that are non-crystalline, non-particulate
solids, but this is more of a practical matter for a synthetic
chemist.
