This group synthesizes a degradable PEG-based polymer by making a copolymer of ethylene oxide with epichlorohydrin followed by elimination of the halide to incorporate degradable ethylene methylene oxide copolymer with ethylene oxide. This polymer degrades as pH 5.0 at 37 C, but is relatively stable over 70 hours at pH 7.4 at 6 C.
