Blends of different ratios of poly(ethylene terephthalate) (PET) and a thermotropic liquid crystalline polymer (TLCP) composed of 40 mol% of polyethyleneterephthalate and 60 mol% of p-hydroxybenzoic acid (Rodrun 3000) have been processed in a laboratory-based film-blowing extrusion apparatus. Gas permeability measurements have been performed on the films in order to evaluate the effect of the mesophase on the transport behaviour of PET films. The transport properties of the blends are dependent upon the state of dispersion of the minor phase; thus, scanning electron microscopy has been conducted on the film surfaces to observe the morphological structure of the TLCP developed during the extrusion process. Moreover, the mechanical properties of the films at 2, l0 and 30% (w/w) TLCP contents have been examined in both the transverse and flow directions.

Abstract

Blends of different ratios of poly(ethylene terephthalate) (PET) and a thermotropic liquid crystalline polymer (TLCP) composed of 40 mol% of polyethyleneterephthalate and 60 mol% of p-hydroxybenzoic acid (Rodrun 3000) have been processed in a laboratory-based film-blowing extrusion apparatus. Gas permeability measurements have been performed on the films in order to evaluate the effect of the mesophase on the transport behaviour of PET films. The transport properties of the blends are dependent upon the state of dispersion of the minor phase; thus, scanning electron microscopy has been conducted on the film surfaces to observe the morphological structure of the TLCP developed during the extrusion process. Moreover, the mechanical properties of the films at 2, l0 and 30% (w/w) TLCP contents have been examined in both the transverse and flow directions.
