“…The published results showed that polymers containing chalcone group have the ability to graft among different polymer chains when exposed to UV radiation. [7][8][9] Derived polymers of chalcone are widely applied to various fields such as microscopy, [12][13] photosensitive materials, nonlinear optical materials, [14][15][16] crystal displays liquid. [17][18][19] Byung-Hak Kim et al had produced melanin by the chalcone derivative 1-(2-cyclohexylmethoxy-6hydroxy-phenyl)-3-(4-hydroxymethyl-phenyl)-propenone (chalcone-21) and this chalcone-21 may be a useful anti-melanogenic agent and effective to the treatment of aesthetic problems and hyperpigmentation disorders.…”

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.

“…The anhydride units can serve various purposes. Alcoholysis can introduce acid groups which are useful for increasing polarity and thus adhesion properties of resist materials 4. The anhydride groups can react with suitable amino group‐bearing polymers to increase the thickness of the resist layer.…”

Functional copolymer/clay hybrids were synthesized by radical‐initiated interlamellar copolymerization of maleic anhydride/maleic acid and acrylic acid with 2,2′‐azobis(2‐methylpropionamidine) dihydrochloride as a water‐soluble ionizable radical initiator in the presence of reactive (octadecylamine‐montmorillonite (ODA‐MMT)) and non‐reactive (dimethyldodecylammonium‐montmorillonite) organoclays at 60 °C in aqueous medium under nitrogen atmosphere. The monomers were dissolved in aqueous medium, and the two types of clay particles used were easily dissolved and dispersed partially swollen, respectively, in deionized water. Structure, thermal behaviour and morphology of the synthesized nanocomposites were investigated using Fourier transform infrared spectroscopy, X‐ray diffraction, differential scanning calorimetry, thermogravimetric analysis, and scanning and transmission electron microscopy. It is demonstrated that intercalative copolymerization proceeds via ion exchange between organoclays and carboxylic groups of monomers/polymers, which essentially improves interfacial interactions of polymer matrix and clay layers through strong hydrogen bonding. In the case of intercalative copolymerization in the presence of ODA‐MMT clay, a similar improvement is provided by in situ hydrogen bonding and amidolysis of carboxylic/anhydride groups from copolymer chains with primary amine groups of ODA‐MMT. The nanocomposites exhibit higher degree of intercalation/exfoliation of copolymer chains, improved thermal properties and fine dispersed morphology. Copyright © 2011 Society of Chemical Industry
