Tin fluorophosphate glass (Pglass) with low glass transition temperature is a relatively new inorganic polymeric glass. During the melt processing temperature of many polymer

the Pglass is liquid. In the present paper

polypropylene (PP)/Pglass composites have been prepared by twin-screw extruder. Moreover

the morphologies

interface properties

rheology properties

crystallization behavior

tensile properties and thermal stability have been investigated. The results showed the Pglass particles dispersed in the PP matrix with a micrometer diameter

and phase interfacial was clear and the compatibility was poor. With the addition of Pglass the shear viscosity of the composites decreased. The crystalline properties increased with the Pglass content. The composites had much larger elasticity modulus than that of pure PP. The thermal stability of the composites increased.
