Patent number: 9029489Abstract: The invention provides intermediates of the formula: as well as a method of their preparation by reacting a thiol having at least two hydroxyl groups with a mono-unsaturated organic compound in the presence of a base catalyst. A polymerizable urethane acrylate oligomer or urethane methacrylate oligomer is formed by reacting a polyisocyanate with the intermediate. The polymerizable urethane acrylate oligomer or urethane methacrylate is blended with a polymerization initiator to form a composition which is useful in such applications as adhesives.Type: GrantFiled: June 28, 2010Date of Patent: May 12, 2015Assignee: Dymax Oligomers and Coatings LLCInventors: James H.

Publication number: 20120016050Abstract: Urethane acrylate oligomers, suitable for use in coatings and like formulations, prepared by capping polyols having hydroxyl functionality (fOH) equal to or greater than 4, using 2-isocyanatoethyl acrylate or 2-isocyanatoethyl methacrylate, thereby avoiding the gelation that normally occurs in attempting to prepare urethane acrylates with high/OH polyols by reaction with diisocyanates. Reaction of low molecular weight polyols, containing two or three hydroxyl groups, with mono isocyanate(meth)acrylate monomers produces useful, low viscosity urethane (meth)acrylate oligomers. Specifically, capping of a mole of 2,2-dihydroxymethyl butanoic acid by two moles of 2-isocyanatoethyl acrylate molecules leads to the formation of radiation curable water-soluble liquid monomers that are transparent and soluble in water. Oligomers obtained by capping with 2-isocyanatoethyl acrylate demonstrate enhanced adhesion to glass and stainless steel.Type: ApplicationFiled: December 24, 2009Publication date: January 19, 2012Inventors: Joseph A. Leon, Ahmet Nebioglu, James H. Aerykssen, Richard David Zopf, Igor V. Khudyakov

Patent number: 6932869Abstract: The present invention provides an improved method and apparatus for curing coatings on optical fibers, without creating additional heat and compromising the manufacturing speed of optical fibers. The present invention uses at least one ultrasonic transducer coupled to a component of the optical fiber draw tower, such as the coating die, curing stage device or sheath, to emit ultrasound to the coating of the fiber. The use of ultrasound with current coating cure techniques, such as UV radiation curing, aids in accelerating the coating cure process through the effects of sonolysis, allowing an increase in current manufacturing speeds of optical fibers.Type: GrantFiled: November 15, 2001Date of Patent: August 23, 2005Assignee: AlcatelInventors: Bob J. Overton, Igor V. Khudyakov

Patent number: 6859600Abstract: A coated optical fiber includes a fiber coating having an unblended primary portion on the optical fiber, an unblended secondary portion, and a blended portion intermediate the unblended primary and secondary portions. The thickness of the blended portion is greater than or equal to about 10% but less than 100% of the thickness of the fiber coating. An optical fiber ribbon includes a ribbon matrix similarly having an unblended primary portion, an unblended secondary portion, and a blended portion between the unblended primary portion and unblended secondary portion. A method for fabricating a coated optical fiber or optical fiber ribbon includes applying a primary portion material to the optical fiber or plurality of coated optical fibers, and applying a secondary portion material in a manner selected to provide a blend of the primary portion material and the secondary portion material. An applicator apparatus includes means for performing the described steps.Type: GrantFiled: May 30, 2002Date of Patent: February 22, 2005Assignee: AlcatelInventors: Igor V. Khudyakov, Nicholas V.
