From starting materials of succinic acid, fumaric acid and 1,4- butanediol, a series of poly (butylene succinate-co-butylene fumarate)s [P(BS-co-BF)] bearing various BF comonomer molar contents were synthesized. Subsequently, the carbon double bonds involved in the copolyester main chain were subjected to dihydroxylation with catalyst of osmium tetroxide (OSO4) , 7V-methyhnorpholine ./V-oxide (NMO) and water to prepare novel biodegradable copolyesters bearing hydrophilic hydroxyl pendant groups. Moreover, these synthesized copolyesters were further characterized by NMR, FT-IR, DSC.

Key words: succinic acid;fumaric acid;BUTANEDIOL;OSMIUM OXIDE;MORPHOLINE P, HYDROXYLATION;NMR;FT;IR;STRUCTURE CHARACTERISTICS;POLYMER
