Thermogelling properties of injectable functionalized hydrogels
Original language description
Proposed work deals with preparation, characterization and rheological study of well-defined smart injectable hydrogels from biodegradable, biocompatible, controlled life-time copolymers based on hydrophilic poly(ethylene glycol) (PEG) and hydrophobic poly([(lactic acid)-co-(glycolic acid)] (PLA/PGA) copolymer. Thermosensitive PLGA-PEG-PLGA copolymer with PLGA/PEG weight ratio of 1.5; 2; 2.5; 3.0 and LA/GA molar ratio equal to 2.4; 3.0 and 3.4 were prepared and additionally functionalized by itaconic anhydride (ITA) bringing both reactive carbon double bonds and functional -COOH groups to polymer both ends. Aqueous solutions of both modified and unmodified copolymers are able to form free flowing sol at room temperature and clear gel at temperature around 37 deg.C. Therefore, sol-gel transitions, thermogelling and viscoelastic properties were investigated using both test tube inverting method (TTIM) and rheometer. Combined methods give comprehensive information about changing in color,
