Improvement the Thermal Stability of PBT/Cloisite 30B Modified by APS

Nanocomposites of Poly(butylene terephthalate) (PBT)/modified montmorillonite organoclay were prepared via in-situ polymerization of terephthalic acid and butanediolin the presence of different clay content. Cloisite 30B, a commercially available amino modified montmorillonite, wasmodified with 3-aminopropytriethoxysilane (APS) through a silylation reaction in our previous work. [1] Morphology and thermal properties of all samples were investigated using,Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA).
