Abstract
A method of manufacturing a multimode optical transmission medium from a synthetic resin having the distribution of refractive index varying continuously in a fixed direction. In the method, the polymerization is caused to proceed utilizing the effect of diffusion or exclusion of a monomer in the gel formed at the polymerization initiating terminal. Therefore, this method is free from the defects of methods using conventional polymerization reactions, and has an extremely high productivity.
