Abstract
A polycaprolactone fumarate copolymer useful as a material for a biocompatible scaffold for tissue engineering applications is disclosed. The copolymer includes at least one caprolactone unit, at least one fumarate unit, and at least one third unit selected from the group consisting of acrylate units and styrenic units. A linking moiety forms a link between the third unit and at least one caprolactone unit or at least one fumarate unit. The linking moiety can be photodegradable. In one form, the third unit includes at least one methyl methacrylate unit. The copolymer can be used to form the wall of a nerve conduit.
