Phenylthioethyl acrylate
Phenylthioethyl acrylate, identified by CAS number 95175-38-5, is a specialized monofunctional monomer characterized by the presence of a thioether linkage and a phenyl group. This unique molecular architecture imparts specific physical properties, most notably a high refractive index and excellent compatibility with various resin systems. As a liquid monomer, it exhibits relatively low viscosity, making it an effective reactive diluent in formulations where maintaining flow characteristics while enhancing optical performance is critical.
In industrial and research settings, this compound is valued for its ability to modify the mechanical and optical attributes of polymers. The sulfur atom within the thioethyl chain contributes to improved adhesion and toughness in the final cured matrix. Due to its acrylic functionality, it undergoes rapid polymerization when exposed to ultraviolet light or electron beam radiation in the presence of suitable initiators. Users should handle this material with standard precautions for acrylates, ensuring adequate ventilation and protective equipment to manage its potential as a skin and eye irritant.
• The primary application of Phenylthioethyl acrylate lies in the production of high-performance optical coatings and lenses. Its high refractive index allows for the development of thinner, lighter optical components without sacrificing light-bending capabilities. It is frequently incorporated into formulations for brightness enhancement films, light guide plates, and specialized displays where clarity and refractive precision are paramount.
• This monomer serves as a crucial component in the formulation of UV-curable adhesives and sealants. The inclusion of the phenylthio group enhances the wetting properties and surface adhesion to various substrates, including metals and high-energy plastics. Its relatively low shrinkage during the polymerization process helps maintain structural integrity and bond strength in precision assembly applications, particularly in the electronics and optoelectronics industries.
• Phenylthioethyl acrylate is utilized as a specialized reactive diluent in photopolymer resin systems. By reducing the overall viscosity of the formulation, it facilitates easier processing and application while contributing to the final cross-linked network. Unlike traditional diluents that might degrade optical or mechanical properties, this monomer maintains a high refractive index and improves the chemical resistance and thermal stability of the resulting polymer matrix.
