| Abstract: | Eight novel poly(phosphate esters) were synthesized by the solution polycondensation of 1,4 dihydroxy 2,3 naphthalene dicarboxylic acid diethyl ester(DHNE) and phosphoryldichlorides. Their chemical structures were characterized by 1H NMR,IR and elementary analysis, and the molecular weights were measured by VPO method. Their in vitro degradation behavior was studied. The controlled release of an anti tumor drug, 5 fluorouracil, from the matrices of some of these polymers was traced by HPLC. |
