The conventional wisdom is that concentration dependence of the rubbery plateau modulus of polymer solutions is independent of the material. However, in industrial practice, sometimes a small addition of miscible liquid lowers the modulus signiÐcantly whilst at other times it hardly a †ects it. This
It is shown that the glass temperature (T,) for homopolymers of the type 4 H p CXYcan be expressed by a simple additive equation involving two terms: (1) a parameter E which is directly related to the molar cohesion energy and (9) a parameter E.\* which is a measure of restricted rotation about vale
