Abstract
A method of continuous application of a graded index plastics optical fiber in which the refractive index is highest in the center and decreases progressively towards the periphery, said fiber having a plurality of layers of resin deposited concentrically, the method comprising making a plurality of mixtures, each mixture comprising at least one polymer P and a reactive diluting agent including at least two monomers, then depositing said mixtures in the form of coaxial layers, allowing interdiffusing to take place between the layers, and finally crosslinking the polymer P and/or the reactive diluting agent.
