摘要：

Thermal sampling technique in polymers near T-g has disclosed processes obeying a compensation law. It is shown that a distributed process with a single relaxation time having a structure dependent activation energy through coupling with free volume changes, ever occurring at T-g, may explain the observed compensation laws.
