Abstract: A coating composition including a reinforcing agent. The coating composition may include one or more radiation-curable monofunctional monomers, one or more radiation-curable multifunctional monomers or oligomers, a photoinitiator, and a reinforcing agent. The monofunctional monomers, multifunctional monomers, and multifunctional oligomers may include acrylate groups. The reinforcing agent may be an acrylic co-polymer that includes two or more repeat units. At least one of the repeat units includes chemical groups that enable self-association of the acrylic co-polymer. Self-association of the acrylic co-polymer may improve the tensile strength of coatings formed from the coating compositions.

Abstract: An optical fiber is disclosed that includes a primary coating formed from a radiation curable composition that includes a curable cross-linker essentially free of urethane and urea functional groups, a curable diluent, and a non-radiation curable component comprising (thio)urethane and/or (thio)urea groups. The primary coating features low Young's modulus, low Tg, and high tensile strength. The optical fiber exhibits low microbend losses in wire mesh drum and basketweave tests.

Abstract: A low cost composition that cures rapidly and which is suitable for coating an optical fiber comprises at least one ethylenically unsaturated monomer; at least one photoinitiator; and at least one non-radiation-curable polar polymer having pendent groups that facilitate low energy chemical bonding, hydrogen bonding, dipolar interactions or other interactions with radical compounds formed during polymerization of the monomer. The non-radiation-curable polar polymer(s) are inexpensive and reduce and/or eliminate the need for expensive urethane acrylate oligomers, without sacrificing properties, and while achieving rapid cure speeds.

Abstract: A method of synthesizing urethane-free polyfunctional acrylate compounds. The method includes reaction of a polyol with acrylic acid in the presence of an inhibitor. A catalyst may also be present. The catalyst may be an acid and the inhibitor may be a substituted phenol compound. Excess acid may be removed by adding a salt and excess water may be removed by adding a drying agent. The reaction converts alcohol groups of the polyol to acrylate groups to provide a radiation-curable polyfunctional acrylate compound. The reaction is applicable to polyols generally and provides a scalable high yield process for forming urethane-free polyfunctional acrylates over a wide range of molecular weights. Coatings made from the acrylate products exhibit modulus and tensile strength characteristics favorable for primary fiber coatings.
