Abstract
A method for making oligomers is described. The method includes reacting a polyol with a precursor having mixed functionality. The precursor includes a curable functional group and an isocyanate group capable of reacting with an alcohol group of the polyol. The precursor reacts with the alcohol group of the polyol to form a urethane linkage and to add a covalently bonded curable functional group to the polyol. The oligomers can be included in coating compositions for optical fiber and lead to coatings having improved tear strength.
