| OTHER INFORMATION |
|
4-Dioxanone is a monomer to produce biodegradable polymers which are instable by hydrolysis or enzymatic ester linkage cleavages in the presence of water. Monomers of biodegradable polymer have heteroatom-containing structure such as lactones, hydroxybutyric acids, lactides, glycolides, anhydrides and phosphazenes. Other biodegradable polymers include starch, cellulose, and chitosan which refer to the natural polymer. Biodegradable polymers have applications in the field of medical devices, controlled-drug-release, and tissue engineering. |
