Definitions

  • This invention relates to a liquid composition comprising silicone oligomers.
  • the composition can be utilized to removably bind optical glass fibers in a ribbon.
  • Optical glass fibers can be used to carry signals between devices. Individual optical glass fibers that are to run together for a distance are conventionally removably bound together in a ribbon.
  • the ribbon is produced by applying a coating composition to juxtaposed optical glass fibers.
  • each optical glass fiber be properly connected to the device receiving or transmitting the signals or to the end of another optical glass fiber.
  • both ends of each optical glass fiber in the ribbon must be located.
  • Optical glass fibers are conventionally located by color coding each optical glass fiber with a different color. Individual optical glass fibers are partially broken out of the ribbon to permit connections to be made. Ribbon coatings are unsatisfactory if they do not have the requisite low tear strength to permit individual optical glass fibers to be partially broken out of the ribbon without destroying the ribbon coating surrounding other optical glass fibers in the ribbon.
  • Ribbon coatings are also unsatisfactory if they adhere too strongly to the optical glass fiber thereby removing some or all of the color coding when the optical glass fiber is broken out which can lead to confusion and improper connections.
  • Ribbon coatings are also unsatisfactory if they do not have a sufficiently high modulus to withstand the physical forces that occur during the manufacture and use of the ribbon.
  • An optical glass fiber experiences different attenuations at different temperatures. Attenuation is a reduction in strength of the signal carried by the optical glass fiber and is due to stresses developed in the optical glass fiber caused by the temperature change.
  • An attenuation as low as possible is preferred and further a constant attenuation over a wide range of temperatures is preferred.
  • Many ribbon coating compositions do not help maintain a constant attenuation, but instead increase the attenuation.
  • liquid compositions of the present invention include unique silicone oligomers and can be utilized as ribbon coating compositions for releasably binding juxtaposed optical glass fibers in a ribbon. These liquid compositions overcome the shortcomings of the prior art ribbon coating compositions.
  • This invention is directed to a liquid composition
  • a liquid composition comprising (1) a silicone oligomer comprising a group derivable from an alkoxylated silicone, at least two groups chosen from the group consisting of urethane and urea groups obtained from a polyisocyanate, and at least one ethylenical unsaturation and (2) at least one polyfunctional cross-linking agent.
  • the invention further relates to a liquid composition comprising (1) a silicone oligomer obtainable by reacting an alkoxylated silicone comprising at least one functional group chosen from the group consisting of hydroxy groups and amine groups, at least one polyisocyanate and at least one hydroxy functional ethylenically unsaturated monomer and (2) at least one polyfunctional cross-linking agent.
  • the mole ratio of silicone: polyisocyanate:ethylenically unsaturated monomer utilized to produce the silicone oligomer is preferably about 1:1.5:1.5 to about 1:4:4.
  • US-A-4.136.250 a silicone oligomer is described that is derivable from a hydroxyterminated silicone and a hydroxy terminated acrylate reacted with a diisocyanate. US-A-4.136.250 however does not describe the use of a polyfunctional cross-linking agent and therefore does not produce the preferential liquid composition of the invention. US-A-4.136.250 is directed to hydrogels and not to a composition that can be used as a binder for optical glass fibers in a ribbon. US-A-4.136.250 is hereby incorporated by reference with respect to the description of the silicone oligomer.
  • the liquid composition can be applied to coat an optical glass fiber.
  • optical glass fiber refers to a fiber made of glass and used in an optical application, but a fiber of any other material can be coated with a liquid composition according to the invention and be applied in any other field.
  • the liquid composition is applied to optical glass fibers.
  • the liquid composition can be utilized to produce a ribbon coating that releasably binds juxtaposed optical glass fibers in a ribbon.
  • the cured ribbon coatings of the present invention have a low tear strength that permits an optical glass fiber to be easily broken out from the ribbon without adversely affecting the remainder of the ribbon.
  • the cured ribbon coatings of the present invention have an adherence to the optical glass fiber that is strong enough to produce a ribbon but not strong enough to remove the color coding from the optical glass fiber coating when the fiber is broken out of the ribbon.
  • the ribbon coatings of the present invention exhibit good break-out properties.
  • the cured ribbon coatings have a high modulus that permits the ribbon to withstand the physical forces exerted thereon during the manufacture and use of the ribbon.
  • the physical properties of the ribbon coating are relatively stable over a temperature range to which the ribbon is conventionally exposed, i.e., about -40° to 85°C. It is presently believed that this stability helps maintain a relatively constant attenuation of the strength of the signal carried by the optical glass fiber because the ribbon coating does not stress load the optical glass fiber due to thermomechanical changes to the same extent that conventional materials impart a stress load.
