| 摘要 |
The present invention is directed primarily to an interlinked crystalline solid polyethylene glycol composition (I-PEG) having a molecular weight of at least 20 kDa and a melting temperature of at least 40° C. and its use as an absorbable device having hydrolabile ester or carbonate interlinks that allow in vivo dissociation of the interlinked chain into excretable, low molecular weight PEG segments.
