Abstract

Polymer alloys of poly(ethylene terephthalate)(PET) and nylon6(PA6) which were not miscible each other by themselves were successfully prepared through melt compounding using a twin-screw extruder by utilizing epoxy as reactive compatibilizer. At the epoxy(DGEBA) amount of 0.5~2wt%, the domain size(average diameter) of the discontinuous phase could be reduced up to 0.2${\mu}m$ from 1-5${\mu}m$ that of the simple blend without epoxy. The reaction was presumed to happen mostly at interphase from the result of maximum increase of melt viscosity at the middle range of PET/PA6 blend ratio. It is expected that alloy fibers of PET/epoxy/PA6 with enough mechanical strength for use can be prepared.
