Abstract
A previous theory for the mobility of molecules in glasses near the glass temperature has been extended in an effort to deduce the semiempirical relation proposed by Williams, Landel, and Ferry. By focusing attention upon the free volume, one is able to derive their relation in a straightforward fashion subject to approximations valid near the glass temperature. The interpretation of the constants which WLF proposed for their relation is shown to be correct.Keywords
