Block copolymers were prepared by ring-opening polymerization of epsilon-caprolactone in the presence of monohydroxyl or dihydroxyl poly(ethylene glycol) (PEG), using Zn powder as catalyst. The resulting poly(epsilon-caprolactone) (PCL)-PEG diblock and PCL-PEG-PCL triblock copolymers were characterized by various analytical techniques such as NMR,(More)
BACKGROUND Saphenous vein grafts (SVGs) are frequently used for multi-vessel coronary artery bypass grafting and peripheral arterial bypasses; however, the estimated 40% failure rate within the first 5 y due to intimal hyperplasia (IH) and the subsequent failure rate of 2%-4% per year pose a significant clinical problem.
