This highly anisotropic fibrillar structure should confer a sharp reduction in the viscosity of the anisotropic in situ composite melt (9) that is somewhat similar to that reported for in situ polymer composites reinforced with TLCPs
A thermo-tropic liquid crystal polyester (TLCP
) was also used as a blend component to increase the thermal-oxidative resistance of PET, but the addition of 10 and 20 wt% of TLCP
only increased 1-2[degrees]C of the initial thermal decomposition temperature ([T.sub.onset]) and the 2-3[degrees]C of the maximum thermal decomposition temperature ([T.sub.max]) (6).
Scattering from rigid rod-like TLCP
molecules is concentrated perpendicular to the underlying molecular orientation direction.
(3) to describe the general morphological features of TLCP
Because of the unique role that TLCP
plays in the reinforced polymer blends, blending a nanocomposite of high viscosity with TLCP
is a feasible method to improve its processability without damaging other properties.
In this study, well-dispersed PA6/clay nanocomposite was used to blend with a commercial TLCP
(Vectra A950 from Hoechst Celanese).
Extensive studies are made about properties of TPE material reinforced with thermotropic liquid-crystalline polymer (TLCP
) fiber (6-11).
DePolo and Baird (13) found that 6 mm long pregenerated thermotropic liquid crystalline polymer (TLCP
) microfibrils (from 0 to 40 wt%) significantly increased (from 3% to 18%) the warpage of their PP parts while reducing the value of the flow directional shrinkage by 1% and the cross-flow shrinkage by 0.3%.
In this study, TLCP/PEI in-situ composites, based on the direct introduction of a small amount of TLCP
that is miscible with PEI matrix without compatibilizer, has been made and investigated.
Blending thermotropic liquid crystalline polymers (TLCP
) with thermpoplastics permits the design of new high-performance composite materials with high strength and stiffness.
In this article, we present a simple method to substantially reduce the undesirable built-in anisotropy by dividing the flowing TLCP
melt into small streams by passing it through an open-celled metal foam structure (porous medium) that naturally provide a medium in which micro-channels of varying cross-section and direction apply substantial amount of shearing throughout the body of the flowing fluid.
