Abstract
By interfacial esterification of sucrose with methacryloyl chloride, an ester derivative of sucrose—methacryloyloxysucrose was prepared, which contains vinyl side groups. The structure of methacrylated sucrose (MS) was determined by means of FTIR, 1H NMR, and 13C NMR spectra. The MS was used as new cross-linker to cross-link poly(2-hydroxyethyl methacrylate). The influence of the amounts of cross-linking agent on the swelling behavior of these hydrogels was studied. Differential scanning calorimetry (DSC) was used for measuring the different states of water in hydrogel materials. DSC date showed that the content of freezing water in hydrogel decreased with growth of MS percentage.
