摘要：A method of manufacturing a multimode optical transmission medium from asynthetic resin having the distribution of refractive index varying continuously in a fixeddirection. In the method a monomer is polymerized while a transparent polymer forconstituting the wall of a vessel is being resolved into the monomer. Therefore, thismethod is free from the defect of methods using conventional polymerization reactions,and has an extremely high productivity.
