Abstract

High performance polymers require new processing technologies to achieve their full potential properties. The strength, stiffness, coefficient of thermal expansion, and barrier properties of LCPs and blends are strongly dependent on processing. The use of biaxial shear flow during extrusion, elongational strain after extrusion, electromagnetic field effects, and thermal treatment will be discussed with respect to LCP film processing. The effect of these conditions on the properties of films will be reviewed and applications for high barrier containers, electronic substrates and lightweight structures will be described.
