ABSTRACT:
The present invention relates to provide a drawn optical transmission medium having excellent heat resistance and a continuous refractive index distribution in a good productivity at a low cost, and the disadvantages in a conventional synthetic resin optical transmission medium can be eliminated, which method is characterized by a step of crosslinking a polymer having a continuous refractive index gradient distributed from the peripheral portion to the central portion in its cross section and having a crosslinkable functional groups, after the step of heating and drawing.
