文摘

Glass transition temperature T_g values characterize pure polymers, polymer blends, copolymers, as well as matrices in polymer-based composites. T_gs as function of composition reflect miscibility (or lack of it) and determine all properties. We present a new equation for the dependence of T_g on composition in blends as well as in copolymers. We compare results obtained from earlier equations (Fox, Gordon–Taylor, Kwei) and those from the new equation with experimental data.
