摘要：

An extended Williams-Landel-Ferry equation is derived within the free volume approximation. This equation relates the jump frequency of an arbitrary molecule (around the glass transition temperature) to the segmental jump frequency at the glass transition temperature. The connection with the usual WLF equation is discussed.
