摘要：

Glass transition temperature T, values characterize pure polymers, polymer blends, copolymers, as well as matrices in polymer-based composites. T(g)s 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. (c) 2008 Elsevier B. V. All rights reserved.
