ABSTRACT:
A heat-resistant plastic optical fiber having a concentric three-layered structure comprising a core layer, a sheath layer and a protective layer, wherein the polymer constituting the sheath layer is a copolymer comprising 30 to 80 mole % of a fluorodioxole represented by the general formula: ##STR1## wherein R and R' are each a fluorine atom or a trifluoromethyl group, and 70 to 20 mole % of at least one other comonomer. Also, a process for the production of the heat-resistant plastic optical fiber comprising spinning a core-forming polymer, a sheath-forming polymer and a protective layer-forming polymer by a three-layered conjugate spinning process.
