Investigation and Preparation of High Impact Polystyrene Nanocomposites

Abstract

A series of polymer -organoclay nanocomposite materials consisting of polystyrene (PS) and high impact polystyrene (HIPS), layered montmorillonite organo clay (MMT) were prepared by dispersing nanophase in the organic PS matrix via in situ thermal polymerization. The nanocomposite effects on the chemical resistance and mechanical properties modification of PS and HIPS were investigated and characterized by XRD, SEM, chemical and mechanical testing. The results show That HIPS /organo clay nanocomposites have the best chemical resistant.

Coupling Effect of Mechanical and Thermal Rejuvenation for Polystyrene: Toward High Performance of Stiffness, Ductility, and Transparency

“…As one of the most promising transparent materials, polystyrene (PS) has exhibited excellent applicability due to its remarkable rigidity and stiffness, − outstanding optical properties, , good electric performance, , chemical resistance, , and dimensional stability. , However, because of the rather poor ductility, PS has yet to fulfill its promise to replace other optically clear polymers such as polycarbonate . Excluding the conventional rubber-toughening method, mechanical rejuvenation is regarded as an effective way to solve its inherent brittleness.…”
