Investigation on the kinetic mechanism of structure healing for block copolymer materials after large elongation

The kinetic mechanism of structure healing after unloading from large elongation for styrene–butadiene–styrene (SBS) block copolymer materials was investigated by following their residual deformation recovery behaviors upon annealing. A linear relationship was found to exist between the deformation...

description The kinetic mechanism of structure healing after unloading from large elongation for styrene–butadiene–styrene (SBS) block copolymer materials was investigated by following their residual deformation recovery behaviors upon annealing. A linear relationship was found to exist between the deformation recovery percentage and the logarithm of time at different temperatures, which shed light on the mechanism of structure healing. A modified activation energy model was proposed to describe the kinetics of the process. It was also found that the model agrees well with other SBS structure healing–related experimental data such as the recovery of hardness as well as dynamic mechanical property after large elongation. © 2004 Wiley Periodicals, Inc.
