UNEXPECTED RHEOLOGICAL BEHAVIOR OF NOVEL LOW-Tg TIN FLUOROPHOSPHATE GLASS/POLYAMIDE 6 HYBRIDS WITH ENHANCED BENEFITS

摘要

By incorporating special low glass transition inorganic tin fluorophosphates glass (Pglass) into polyamide 6, the latter exhibits unprecedented non-Einstein-like viscosity decrease in the liquid state and an increase in Young's modulus in the solid state. This behavior makes the hybrid Pglass/polymer solid material stronger yet easier to process in the liquid state. The linear rheological behavior is discussed in terms of the hybrid components rheology. The results should beneficially impact our ability to prepare lower viscosity, highly filled polymers using already existing polymer processing methods, making the simple strategy potentially widely applicable in a number of applications such as barrier resistant thin films and flame-retardant polymer composites.
