Synthesis of side-chain liquid-crystalline cinnamide polymers based on post polymer reaction
We prepared novel photoreactive liquid crystalline (LC) polymer via polymer reaction. The cinnamic acid activated ester easily converted to amide by mixing with amine derivative and solubility of the polymer reduced due to hydrogen bonding. Upon exposure
MULTI-FUNCTIONAL MONOMER HAVING A PHOTOREACTIVE GROUP, ALIGNMENT FILM FOR LCD USING THE MONOMER, AND LCD COMPRISING THE ALIGNMENT FILM
Disclosed is a multi-functional monomer including a heat-curable functional group as well as a typical photoreactive group. In the multi-functional monomer, the photoreactive group is not chained to a main chain of a polymer. Thus, since it is possible to
