| Abstract: | Poly(trimethylene terephthalate)(PTT)/poly(butylene terephthalate)(PBT) blend and its ternary systems reinforced by carbon nanotubes(CNTs) were prepared by melt-mixing.The effect of CNTs on the transesterification between PTT and PBT was then studied through nuclear magnetic resonance spectroscopy(NMR).The possible mechanisms were then discussed preliminarily according to the observations by transmission electron microscopy(TEM) scanning electron microscopy(TEM) and sedimentation experiments,as well as the ... |
