Abstract
An electro-optic polymer includes a backbone that is a polynorbornene chain and an electro-optic structure at a side chain on the backbone. The polynorbornene chain has a first constituent unit represented by: wherein at least one of X1 or X2 is a binding site between the polynorbornene chain and the electro-optic structure, when X1 is the binding site, X2 is —O— or —NH—, when X2 is the binding site, X1 is a hydrogen atom or substituted or unsubstituted alkyl group, and nA2 is an integer of 1 or greater.
