Patent number: 6579914Abstract: A composition for coating an optical waveguide, more specifically, an optical fiber, and optical fibers coated therewith. The coating composition is a radiation curable composition including an aliphatic epoxide, a urethane acrylate oligomer, a reactive diluent, and cationic and free-radical photoinitiators. The cationic photoinitiator acts upon the aliphatic epoxide while the free-radial photoinitiator acts upon the urethane acrylate oligomer. The resulting cured coating forms an interpenetrated polymer network. The properties of coatings in accordance with the invention including the glass transition temperature thereof, can be tailored to achieve advantageous coatings suitable for use as primary coatings and secondary coatings for an optical fiber.Type: GrantFiled: July 14, 2000Date of Patent: June 17, 2003Assignee: AlcatelInventors: Todd W.

Patent number: 6562881Abstract: An alkoxylate adduct of a polyol. The polyol is an amorphous diol having a melting point above about 100° C. The alkoxylate is propylene oxide, butylene oxide, a mixture of propylene oxide and butylene oxide or a mixture of one or both of propylene oxide and butylene oxide with up to 50 mole % of ethylene oxide. The first polyol has an average of from about 1 to about 5 units of alkoxylate per mole of said amorphous diol. The adduct is useful in preparing urethane (meth)acrylate capped resins and compositions thereof. Resins prepared from such adducts have better manufacturing and solubility properties while retaining similar physical properties to resins prepared from the unadducted diol. The adduct may be for instance a propoxylate of hydrogenated bisphenol A having an average of from 1.5 to 3.5 moles of PO per mole of hydrogenated bisphenol A.Type: GrantFiled: May 30, 2001Date of Patent: May 13, 2003Assignee: Henkel Loctite CorporationInventors: Anthony Jacobine, David Glaser
