摘要：

Theoretical developments are presented that explain four experimental observations concerning the temperature dependence of chromatographic specific retention volumes. A theoretical framework is proposed for a method that can be used to determine the glass-transition temperature of the pure polymer and for a method of characterizing the concentration dependence of the glass-transition temperature of a polymer-solvent system.
