A new biodegradable and biocompatible polymer, phosphorylcholine functionalized poly(butylene succinate) (PBS-PC) was synthesized via a four-step synthetic strategy. The results of 1H NMR, IR, gel permeation chromatography (GPC) and X-ray photoelectron spectroscopy (XPS) measurements demonstrated a successful construction of PBS-PC. Dynamic contact angle, in vitro degradation, swelling behavior and drug release measurements revealed that the PBS-PC showed higher hydrophilicity, degradation, swelling and faster drug release rates by using neutral red as a model drug.

Key words: poly(butylene succinate), phosphorylcholine, in vitro degradation, swelling behavior, neutral red, drug release
