Molecular weight distribution and long chain branching were taken into account for the glass transition temperature (Tg)-molecular weight (M) relationships for bisphenol-A polycarbonate. A new form of the four-variable equation for Tg is proposed for polydisperse branched polymers. The extended equa
## Glass-transition temperatures at various water contents (TJ and in maximally freeze-concentrated solutions (T,'), fusion temperatures (melting points, T,), and heats of fusion (Aff,) were determined for pentoses, hexoses, disaccharides, and alditols, using differential scanning calorimetry. The
