Abstract: Three adhesives formulated with Trimethylolpropane Trimethacrylate (TMPTMA) that do not contain BisGMA were developed, whereby the mutagenic and teratogenic risk by the release of bisphenol A is eliminated, and presented a better performance compared to the three commercial adhesives prepared with BisGMA (Adhesive A, Adhesive C and Adhesive B). The invention provides an adhesive used in one-step and provides a system which is formed by a primer and a slurry. The adhesives of the invention were compared with two commercial controls. They were physically characterized by assessing: hardening time, adhesion stress, elastic modulus, sorption and solubility at different pHs (6.8 and 7.7); by the obtained values premature detachments, white lesions below the appliance and microfiltration are avoided; its fluidity, film thickness were evaluated and were compared with those obtained from the three commercial adhesives. Storage stability and thermogravimetric analysis were assessed.

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.
