Zusammenfassung:	PURPOSE:To obtain relatively easily a polymer having an intended refractive index distribution by dipping a circular columnar transparent polymer contg. an epoxy group into a specific swellable liquid to swell said polymer then dipping the polymer into a reactive liquid to diffuse the lower molecular compd. into the polymer and to cause both to react and drying the polymer. CONSTITUTION:A circular cylindrical transparent polymer contg. an epoxy group is dipped in a swellable liquid which satisfies 1.1
