The novel functionalized side-chain polymer wherein p-nitrophenylcarbamate is imbedded into phenoxy resin backbone was synthesized. The orientation of the nonlinear optical chromophore of drawn and poled polymers was analyzed by measuring linear and nonlinear optical properties. The chromophore ratio, i.e., the ratio of monomer unit substituted by 4-nitrophenylcarbamate; was varied from about 28% to 100%, and then physical properties of polymers were characterized. The glass transition temperature (T-g) increased up to 130 degrees C with increasing chromophore ratio due to the formation of hydrogen bonding. We demonstrated that the poling and drawing can control both the in-plane and out-of-plane birefringence by using the functionalized side-chain polymer having a large dipole moment mu and linear molecular polarizability alpha. The measurement of nonlinear optical properties was carried out to confirm the poling condition and orientation of polymer. The ideally uniaxially oriented films were poled parallel to the film-thickness direction by the contact poling method at T-g - 17 degrees C. As the result, the out-of-plane birefringence (Delta n(Z-Y), X = drawing direction, Z = film thickness direction) of the drawn and poled polymer films was increased with increasing applied electric voltage and was independent of the draw ratio. It has been shown that most of the drawn and poled polymer films satisfy the relation of refractive indices such as n(X) > n(Z) > n(Y).
