3.2.3. Solvent

The solvent volume was varied from 5 mL to 13 mL in the formation of GT-cl-poly(DMA) hydrogel (Figure 1c). The maximum swelling (784.4%) was obtained at solvent volume of 11 mL. At higher solvent volume beyond 11 mL, the swelling percentage of GT-cl-poly(DMA) hydrogel was decreased, the excess solvent volume lowered the concentration of KPS, DMA and NMBA resulted in poor degree of polymerization.
