ABSTRACT:
Curable optical fiber cladding compositions that exhibit improved optical, mechanical, adhesive and moisture barrier properties are prepared from a 100% reactive composition of monofunctional and multi-functional monomers. The preferred components of these compositions are low molecular weight polymers of fluorine-containing monofunctional acrylate or methacrylate monomer(s), such polymers being soluble and dissolved in a fluorocarbon acrylate or methacrylate monomer or monomers, but not necessarily those of the base polymer. The preferred cladding compositions may be prepared with or without a cross-linking monomer such as a di-functional or poly-functional acrylate of methacrylate. The claddings may also use a thermal or photoinitiator or other known polymerization initiating system and an adhesion promoter or promoters, such as acrylic or methacrylic acid, a silanol acrylate, methacrylate, alkoxysilane acrylate or methacrylate, or an alkoxy vinyl silane, aryl acrylate or methacrylate.
