Interpenetrating polymer networks based on polyurethane and epoxy based polymer containing phenylazo benzothiazole (BT) chromophore groups were synthesized.Crosslinked polyurethane was obtained by the reaction between (2 hydroxypropyl acrylate BT 2 methacrylate) copolymer and phenol capped NCO terminated BT 1,whereas crosslinked epoxybased polymer was formed by reaction between epoxy containing BT and BT containing aniline.The IPNs were synthesized by carrying out the above two reactions simultaneously,and were characterized by gel content,IR spectra and differential scanning calorimertry.The IPN shows two T g at 142℃ and 170℃.Thin,transparent poled films of the IPN were prepared by spin coating,followed by thermal curing and corona poling at 160℃ for 1h.The second order nonlinear optical properties of the poled films were studied by a visible light absorbance measurement according to the one dimensional rigid oriented gas model.Long term stability of the dipole alignment at 120℃ was demonstrated for the IPN.
