Optical fiber having polymethacrylate core and fluoro-copolymer cladding |
| abstract |
The invention relates to an optical fiber of the step-index type in which the core material is poly(methyl methacrylate) or a copolymer of methyl methacrylate with another methacrylate or an acrylate. A copolymer of vinylidene fluoride with hexafluoroacetone is employed as the cladding material which makes good adhesion to the polymethacrylate core. When the amount of hexafluoroacetone is 4-20 mole %, the copolymer is low in crystallinity, high in transparency, appropriately low in refrax index and higher than 100° C. in softening temperature, and can be extruded under the conditions suited to extrusion of poly(methyl methacrylate). |
