Enthalpy relaxation studies in isotactic polystyrene. Effects of crystallinity

  • Published:
Polymer Bulletin Aims and scope Submit manuscript

Summary

The enthalpy relaxation of the amorphus isotactic polystyrene is strongly affected from the crystalline phase induced by annealing at temperatures between Tg and Tm. All the parameters describing the relaxation process, ΔΔH, Tmax and Tons depend also on the above Tg annealing conditions as the induced crystallinity alters the quantity and the quality (i.e.Tg, Tgons, ΔTg) of the remaining amorphous phase.
