Abstract
This invention relates to a copolymer prepared by polymerizing at least a vinyl compound (A) which gives a homopolymer with a refractive index of 1.50 or more, a fluoroalkyl (meth)acrylate (B) represented by the following formula (1) and methyl methacrylate (C), wherein a weight ratio of monomer (A) component/monomer (B) component ((A)/(B)) in the copolymer is within the range of 0.2 to 1; as well as a plastic optical fiber and a plastic optical fiber cable comprising a clad made of the copolymer. This invention can provide a plastic optical fiber and a plastic optical fiber cable exhibiting a reduced transmission loss, minimizing increase in a transmission loss even when being held as a bobbin-wound form, exhibiting a reduced bend loss and can transmit a wide-band data. (In the above formula, X represents H or CH; and Rf represents fluoroalkyl having 7 to 14 carbon atoms both inclusive and 13 to 25 fluorine atoms both inclusive.).
