Method for fabricating a preform for plastic optical fiber

摘要

A method for fabricating a preform for a plastic optical fiber, comprising: (1) preparing a pair of monomer solutions having different refractive indices; (2) polymerizing a monomer solution having a lower refractive index than the other to form a prepolymer; (3) homogeneously mixing the prepolymer with the other monomer solution to obtain a mixture; and (4) feeding the mixture into a reactor and polymerizing the mixture while the reactor is being rotated. According to the method, a preform for a plastic optical fiber can be fabricated from monomers selected irrespective of their density.
