Since elemental sulfur is a waste of petroleum refining process, Sulfur rich polymer (SRP) is attracting attention as an IR optical material. SRPs are noted for their high IR transmittance and dynamic S-S covalent bonds, which allow for bond exchange at elevated temperatures. Herein, we investigate the properties of SRPs with different crosslinkers, 1,3-diisopropenyl benzene and divinylbenzene. Relatively, poly(S-r-DIB) has high infrared (IR) transmittance and low thermomechanical properties, while poly(S-r-DVB) has low IR transmittance and high thermomechanical properties. To achieve a balance between these two extremes, explore the approach of blending these substances in powdered form. After synthesizing each SRP, we pulverized and mixed poly(S-r-DIB) and poly(S-r-DVB) in various ratios. Then processed windows through hot pressing and measured optical and thermomechanical properties.
