Optical fiber coating compositions with non-curable reinforcing agents

摘要

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.

1. An optical fiber coating composition comprising:
a radiation-curable monomer; a photoinitiator; and an acrylic co-polymer, said acrylic co-polymer including a first repeat unit derived from a (meth)acrylate monomer and a second repeat unit derived from an ethylenically unsaturated monomer, said (meth)acrylate and ethylenically unsaturated monomers differing in chemical composition, said acrylic co-polymer lacking a radiation-curable group.
