    Polyoxyethylene containing chitosan derivatives for the development of hydrogels
    (Видавництво Львівської політехніки, 2013) Zholobko, Oksana; Tarnavchyk, Igor; Demchuk, Zoriana; Voronov, Andriy; Budishevska, Olha; Voronov, Stanislav
    Polyoxyethylene containing derivatives of succinic acid (2SA-PEG) have been synthesized via the acylation of polyethylene glycols with succinic anhydride. Water-soluble chitosan derivatives and films based on them have been obtained through the interaction between 2SA-PEG and chitosan (CS). Water-insoluble films have been developed via crosslinking during thermal treatment of the products of the interaction between 2SA-PEG and chitosan. The films form hydrogels after swelling in water. The hydrogel films, filled with rhodamine G and malachite green dyes, are capable of prolonged releasing them into an aqueous medium.
