摘要：

For a number of polymers, the volume relaxation occurring after quenching from above to below glass transition temperature, T//g has been studied by length dilatometry. By varying the test temperature between minus 180 degree C and T//g, the temperature regions of several secondary transitions were covered. Volume relaxation rate was found to show similar (secondary) peaks as the mechanical damping. The theoretical implications of these findings are discussed.
