Photos residual liquids

The most convenient way to prepare thermosetting gel is to add reactive monomers such as acrylate and metacrylate of the alkylene oxide to the liquid electrolyte and cross-link by irradiating heat, ultraviolet, or electron beam. The residual monomer can be detected by methods of infrared absorption measurement (on basis the peak of 1638 cm ), supercritical fluid chromatography, and photo-DSC (optical difference scanning thermal analysis).
