Vitrigens: Part 2: Low molecular weight organic systems with high glass transition temperatures

Abstract

Low molecular weight organic materials characterized by a strong tendency towards glass formation and by glass transition temperatures around 100°C are considered. They are constructed either as bulky odd-shaped molecules or as twin molecules where two bulky groups are linked via flexible or semi-flexible central groups. The synthesis of such materials, their structure-glass formation relationship and their miscibility with each other and with polymer matrices are described.
