ABSTRACT:
Coating compositions comprising liquid crystalline binders are provided by a combination of mesogenic groups and amorphous resins. The mesogenic groups are either covalently bonded or cross-linked to the amorphous resins to provide coatings of exceptional hardness and toughness. Also provided is an economical process suitable for commercial manufacture of mesogenic compounds and more particularly for the production of liquid-crystalline oligoester polyols.
