Photopolymerizable composition for cladding optical fibers

摘要

A photopolymerizable composition for cladding optical fibers comprises an unsubstituted or fluorosubstituted diacrylate monomer; a fluorinated monofunctional acrylate monomer in an amount of from about 2 to about 12 parts by weight per part by weight of the diacrylate monomer; a photoinitiator; and a viscosity modifying agent to increase the viscosity of the composition to about 1000 to about 15000 cP. Upon photocuring, the composition has a refractive index not greater than about 1.43, and preferably not greater than about 1.40.
