Applications of liquid crystal polymers

The science and technology of liquid crystal polymers is selectively reviewed with an emphasis on those aspects key to successful commercial utility. The importance of the low viscosity demonstrated by nematic polymers under commercial processing conditions, coupled with the low volume change on cooling and high thermal stability associated with these nematogens, is identified as the major factor behind the success of the thermotropic copolyester as a high-performance molding resin. The developing area of side-chain liquid crystal polymers as electro-optical media is discussed, stressing the importance of combining function and processibility for ultimate commercial viability. Potential markets and projected commercial growth rates are discussed from the point of view of the enabling science needed to successfully define and implement new commercial applications for liquid crystal polymers.
