The monomers chalcones derivatives were synthesized by the condensation reactions of the 4‐hydroxy benzaldehyde and vanillin with p‐hydroxyacetophenone. The monomers were polymerized with dibromoalkanes to give the co‐polyethers containing the photocrosslinkable α, β‐unsaturated carbonyl as photosensitizer group. The structure of polyether was characterized by 1H NMR and 13C NMR spectra. The thermal stability of the polymer was measured by thermogravimetric analysis. The solubility of the polymer in the organic solvents was also studied. The polymers have to be equipped with photosensitive functional groups applied in photopolymers technology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
