摘要

CLAIMS 1. A method for producing an optical rod-type indexed polymer preform which is obtained by polymerizing a mixture containing a starting material by spinning to produce a composition of a shell of the plume and a preform composition in the vicinity of the core,;After the mixture of various monomers is rotated and the dispersion of the monomers is achieved, the mixture is rotated to perform the polymerization reaction,;After the monomer and thermosetting polymer-containing mixture (wherein the monomers differ from the monomers making up the polymer) is dispersed, the monomer and polymer are dispersed, and the monomers present in the mixture are then rotated to polymerize,;In both cases, a method is provided for producing an optical rod-type graded index polymer preform which comprises rotating at a diameter according to the rotational speed represented by the following equation:; Equation 1 ;rpm 10,000 d^-0.5;In the formula,;rpm = rotation speed, revolutions per minute,;d = Diameter of preform (cm).;The present invention also relates to an optical lens and an optical fiber produced from the polymer thus produced.
