Abstract
A treated monomer for optical fiber coatings, a coating composition containing the treated monomer, a coating formed from a coating composition containing a treated monomer, and a fiber coated with the coating formed from a coating composition containing a treated monomer. The monomer is an alkoxylated alkyl acrylate and is formed by acrylating a polyol precursor. The monomer may include residual unreacted polyol precursor. The monomer is treated with a derivatizing agent to convert residual unreacted polyol to a derivative form. The derivative form is less susceptible to degradation to the corresponding non-alkoxylated alcohol or other lower alkoxylated alcohol. The treated monomer includes the alkoxylated alkyl acrylate and the derivative form of the polyol.
