AI Technical Summary

Technical Problem

Excessive temperature of existing optical materials during thermoplastic processing leads to thermal decomposition of resin, and is prone to depolymerization at high temperatures, affecting the quality of processing and forming.

Method used

The heterocyclic compound containing disulfide bonds is added to the polymerization system, and the thermal stability of the material is improved through the "bond break-repair" process, the intermolecular force is reduced, the intermolecular force is weakened, and the melting temperature and melt viscosity are reduced.

Benefits of technology

It effectively inhibits the depolymerization of the material at high temperature, reduces the processing temperature, improves the thermal stability and processing and forming performance of the material, and maintains the optical performance with a high refractive index.

Abstract

The present application relates to the technical field of new optical materials, and specifically provides an optical material composition, in which a heterocyclic compound containing a disulfide bond is added to the optical material composition of the polymerization system, and a "bond breaking-repairing" process is completed during high-temperature processing to inhibit depolymerization at high temperatures; at the same time, monomers with difunctional groups are used as the main body to expand the distance between polar molecules in the material, weaken the intermolecular force, and reduce the processing temperature in thermoplastics while maintaining optical properties such as high refractive index.
