20210155639 · 2021-05-27 ·

The disclosure provides recording materials including thiophosphate derivatized monomers and polymers for use in volume Bragg gratings, including, but not limited to, volume Bragg gratings for holography applications. Several structures are disclosed for thiophosphate derivatized monomers and polymers for use in Bragg gratings applications, leading to materials with higher refractive index, low birefringence, and high transparency. The disclosed thiophosphate derivatized monomers and polymers thereof can be used in any volume Bragg gratings materials, including two-stage polymer materials where a matrix is cured in a first step, and then the volume Bragg grating is written by way of a second curing step of a monomer.

Vanillin and vanillyl alcohol were modified into methacrylated derivatives. The structures of vanillin-based monomers were characterized by NMR and FTIR. Renewable polymers were prepared from these vanillin-based monomers. The effects of structure and functionality of the vanillin-based monomers on the thermo-mechanical properties of the resulting polymers were investigated and discussed. Polymers from methacrylated vanillyl alcohol (MVA) demonstrated greater storage moduli, higher glass transition temperatures, and thermal resistance than those from methacrylated vanillin (MV) because of the different functionalities of their monomers.
