Abstract
We have synthesized two classes of polyureas with mono- and diazoaromatic groups in their main chains. Holographic gratings were fabricated on the polyurea films prepared by spin-coating from solutions. Regularly spaced surface relief gratings on the polymer film were also recorded upon exposure to an interference pattern of two polarized argon laser beams.
