Investigating the role of transreactions on degradation behavior of phenoxy/poly(trimethylene terephthalate)/clay nanocomposites using thermal analysis techniques
Original language description
The properties of reactive polymer blends are strongly influenced by the interchange/exchange reactions. The effect of nanofillers on these reactions, in particular transreactions, has not yet fully understood. This work is devoted to investigate transesterification and its consequent effect on degradation behavior of phenoxy/poly(trimethylene terephthalate) (PTT) nanocomposites using thermal analysis techniques. 1H NMR results showed that the maximum extent of transreactions occurred in the blends loaded with just 1 wt.% nanoclay. A mechanism based on nanoconfinement was proposed to show how nanoclay particles affect transreactions of the blend constituents. Thermal degradation kinetic studies, using KAS isoconversion method, revealed that addition ofonly 1 wt.% clay improves thermal stability of the pristine blend whereas higher amount of clay accelerates degradation process. An attempt was made to establish correlations among these changes in thermal degradation behavior, the exten
