    摘要: The plastic optical fiber of this invention has a core comprising a copolymer which comprises, as the essential constituents, a (meth)acrylic ester I represented by the following formula [I]
    wherein R₁ denotes hydrogen or methyl; a (meth)acrylic ester II represented by the following formula [II]
    wherein R2₂denotes hydrogen or methyl, and R₃ denotes C₁-C₈ alkyl, cycloalkyl, or aromatic group; and a multifunctional monomer. The core being formed by heat-curing of the thermosetting resin composition, it provides for a plastic optical fiber with an effect of excellency in the thermal resistance and the mechanical strength. Further, since a fibered polymer can be obtained without a drawing step according to this inven­tion, it gives also an effect of decreasing the light transmission loss caused by a drawing step for plastic optical fibers of the prior art.
