Synthesis and Properties of Biodegradable Copolymers of 9-Phenyl-2,4,8,10-tetraoxaspiro-[5,5] undcane-3-one and Ethylene Ethyl Phosphate
摘要:
Novel biodegradable copolymer poly(CC-co-EEP) was synthesized by ring-opening copolymerization of cyclic carbonate 9-phenyl-2, 4, 8, 10-tetraoxaspiro-[5, 5]undcane-3-one (CC)and ethylene ethyl phosphate (EEP). The obtained poly (CC-co-EEP)s were characterized by FTIR, 1H NMR, 13C NMR and gel permeation chromatography (GPC). In vitro hydrolytic degradation of the copolymers were investigated in phosphate buffer solution (pH=7.4).Hydrophilic phosphate units apparently improved the degradability of poly(carbonate-phosphate).
