Synthesis and properties of some polyethers from chalcones

Abstract

The monomers chalcones derivatives were synthesized by the condensation reactions of the 4-hydroxy benzaldehyde and vanillin with p-hydroxyacetophenone. The monomers were polymerized vvith 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 technoiogy.
