Abstract
A morphological study of poly(butylene terephthalate) (PBT)/polyethyle ne (PE)/ethylene vinyl acetate (EVA) ternary blends is presented. Scan ning electron microscopy analysis illustrates that, after the addition of a transesterification precursor (Bu2SnO), the blend forms a compos ite droplet morphology where the PBT/EVA copolymer, synthesized in sit u creates a boundary layer between the incompatible PET matrix and PE dispersed phase. Electron microprobe analysis is used to localize Bu2S nO in the PET and EVA phases, where it would be expected to favour the formation of the copolymer at the interface.
