Abstract

Degradable copolymers of desaminotyrosyl-tyrosine ethyl ester (DTE) and poly(ethylene glycol) (PEG) have been developed. These polymers can be formulated as hydrogels that collapse or as polymer solutions that solidify upon warming. The copolymer structures were identified using nuclear magnetic resonance spectroscopy (NMR) and Fourier transform infrared spectroscopy (FTIR). The glass transition temperature was determined by differential scanning calorimetry (DSC). Thin compression molded copolymer films were tested on a Sintech 5/D tensile tester at room temperature. Water content of the copolymer films was evaluated by thermogravimetric analysis.
