Abstract

Abstract A photocrosslinkable liquid crystalline polymer comprising a vinyl backbone having from 60 to 100 mole percent of recurring pendant groups comprising an alkyl or alkoxy light-sensitive cinnamate component connected to the vinyl backbone through a) a component which provides stiffness and rod-like character to the cinnamate component and b) a spacer group having a backbone of from 7 to 14 atoms.
