F. Decandia et al., SOLVENT CRYSTALLIZED SYNDIOTACTIC POLYSTYRENE - THERMAL AND DYNAMIC-MECHANICAL BEHAVIOR, Colloid and polymer science, 271(5), 1993, pp. 454-459
The syndiotactic polystyrene can crystallize in different forms, depen
ding on thermal and solvent treatments. The influence of the polymorph
ism on the dynamic-mechanical behavior has been analyzed. Thermogravim
etric and calorimetric analysis were also carried out. The effects of
phase transitions and solvent release on the relaxation phenomena were
observed, and the correlations between structure and dynamic behavior
allow to better understand some aspects of the polymorphism phenomena
