Abstract

A series of poly(ethylene oxide) (PEO)/poly(epsilon -caprolactone) (PCL) containing biodegradable poly(ether ester urethane)s, covering a wide range of compositions, were synthesized and characterized. The synthesis consisted of a two-step process. During the first step, the ring-opening reaction of epsilon -caprolactone was carried out, initiated by the hydroxyl terminalgroups of the PEO chain. The second step involved the chain extension of these PCL-PEO-PCL trimers with hexamethylene diisocyanate. By varying eitherthe ethylene oxide/epsilon -caprolactone ratio or the length of both segments, we obtained a series of polymers having different morphologies and displaying a broad range of properties.
