Poly(5‐benzyloxy‐trimethylene carbonate‐ co ‐glycolide) random copolymers were synthesized through the ring‐opening polymerization of 5‐benzyloxy‐trimethylene carbonate and glycolide (GA). The copolymers with different compositions, PBG‐1 with 17% GA units and PBG‐2 with 45% GA units, were obtained. Using these copolymers, microsphere drug delivery systems with submicron sizes were fabricated using an “ultrasonic assisted precipitation method.” The in‐vitro drug release from these microspheres was investigated. © 2009 Wiley Periodicals, Inc.
