Hydrogels based on cellulose comprising many organic biopolymers including cellulose, chitin, and chitosan are the hydrophilic material, which can absorb a
The just-obtained PECE block copolymers were dissolved in dichloromethane, and then reprecipitated from the filtrate using excess cold petroleum ether. Then, the mixture was filtered and vacuum dried to constant weight at room temperature. The purified copolymers were kept in air-tight bags before ...
