Abstract

The reactive extrusion of a compatibilized polyethylene terephthlate and thermotropic liquid crystalline copolyester blend system is investigated via in-line optical microscopy and light scattering. The reactivity, morphology, rheological behavior and mechaanical properties were investigated. It was found that the droplet-fiber transition in the liquid crystalline polymer is dependent upon the reactivity, the viscosity ratio and the shear fields. The fibers are strongly oriented along the flow direction when specific processing conditions are met. The enhancement in the mechanical properties correlates with the morphology. The formation, deformation and stability of fiber microstructure under different flow conditions are discussed.
