Abstract
A monomer having a free-radical polymerizable methacryloyl group and a photocrosslinkable functional group (pendant chalcone unit) was synthesized and polymerized in MEK at 70°C using benzoyl peroxide as an initiator. The prepared polymer was characterized by UV, IR, 1 H-NMR and 13 C-NMR spectra. The molecular weights ( M w and M n ) of the polymer were determined by gel permeation chromatography. The thermal stability of polymer was assessed by thermogravimetric analysis of the polymer in air/nitrogen atmosphere. The glass transition temperature of the polymer was determined by differential scanning calorimetry. The photocrosslinking property of the polymer was studied as a thin film, and in solution, and the results were discussed.
