Abstract
PURPOSE:To obtain an optical fiber having an excellent photoconduction loss characteristic by cleaning the polymer of a core component with a non-soluble org. solvent at the time of producing the optical fiber having a core-sleeve structure in which a polymer essentially consisting of methacrylic n-butyl as the core component and a polymer contg. at least 20wt.% fluorine as the sleeve component. CONSTITUTION:The polymer consisting of the methacrylic n-butyl is used as the core component and the transparent resin having the refractive index smaller by at least 3% than the refractive index of the core component is used as the sleeve component. Namely, the polymer of the core component is cleaned with the non-soluble org. solvent at the time of producing the optical fiber having the core-sleeve structure in which the polymer essentially consisting of the methacrylic n-butyl is used as the core component and the polymer contg. at least 20wt.% fluorine is used as the sleeve component. The adhesiveness between the sleeve component and the core component is thereby improved and the transparent sleeve component having excellent mechanical strength such as flexibility is stably formed. Methyl or ethyl alcohol, n-propyl alcohol, etc., are used for the non-soluble org. solvent.
