Abstract
The present invention relates to a composition for preparing optical fiber coatings, the composition including a polymerizable base composition, containing at least one monomer and optionally at least one oligomer, wherein the polymerizable base composition is substantially free of unsaturated epoxidized diene polymers, and a tackifier present in an amount effective to modify a time-sensitive rheological property of a polymerization product of the composition. Another aspect of the present invention relates to a method of modifying a time-sensitive rheological property of an optical fiber coating by introducing into a polymerizable composition a tackifier in an amount effective to modify a time-sensitive rheological property of the polymerization product of the polymerizable composition. Also disclosed are an optical fiber, a fiber optic ribbon, and a fiber bundle that contain coating(s) prepared from a composition of the present invention.
