摘要
Disclosed is a cladding composition suitable for a plastic clad silica or glass core optical fiber of a good light transmittance. The cladding composition comprises (A) a fluorinated monofunctional acrylate or alpha -fluoroacrylate composition, (B) a polyfunctional acrylate or alpha -fluoroacrylate having at least two acryloyl or alpha -fluoroacryloyl radicals in the molecule, (C) a photoinitiator, and if desired, (D) a stabilizer selected from thiodicarboxylic acid diesters and hindered phenols. The fluorinated monofunctional acrylate or alpha -fluoroacrylate comprises l - 60 weight % of a highly fluorinated acrylate or alpha -fluoroacrylate of the formula: CHEM wherein Y is H or F, X is H or F, l is l to l2 and n is 5 to l2, and 40 - 99 weight % of a lowly fluorinated acrylate or alpha -fluoroacrylate of the formula: CHEM wherein X and Y are as defined above, and m is l to 3. yla
