We synthesized novel UV-curable sulfur-modified di-functional acrylates with high refractive indices. The structures of monomers were confirmed by nuclear magnetic resonance spectroscopy (NMR) and Fourier transform infrared spectroscopy (FT-IR). The UV-curable formulation was prepared by sulfur-modified di-functional acrylates, bisphenol A epoxy acylate as the oligomer, and α-hydroxy-α-methylpropiophenone as the photoinitiator. The properties of UV-cured coatings such as Taber abraser tests, transmittance, and refractive index were examined. Also thermal analysis of coatings was evaluated by thermogravimetric analysis (TGA) and dynamic mechanical analysis (DMA). |
