respectively. A Fourier transform infrared spectrophotometer, scanning electron
microscope and thermogravimetric analyzer were used for the characterization of
the hydrogels. The swelling behavior of the hydrogels in aqueous solution were
investigated at pH 6.0 and 25°C. The results showed that swelling
characteristics were affected by 2-dimethylaminoethyl methacrylate content of
the copolymeric hydrogel. The swelling degree of hydrogels </span> </font> <span lang="en-us" style="font-family:’Times New Roman’, serif;font-size:11pt;" xml:lang="en-us">increased from 4.2 g g <sup> <font size="2">–1 </font> </sup>
