Optically Induced Birefringence in Copolymers and Blends Containing Azobenzene Groups

Abstract

The birefringence level in a copolymer or a blend containing disperse red 1 acrylate or methacrylate structural units depends not only on the molar fraction of the azo component, but also on the type of the next-neighbor on the chain. Copolymers behave quite differently from blends. Also, if a few azo groups are neighboring each other, the induced birefringence is more stable.
