Abstract

Improved methods for preparing polyethylene glycol fumarate) are disclosed. Methods for chemically crosslinking or photocross-linking hydrophilic polyethylene glycol fumarate) with hydrophobic polymers such as poly(propylene fumarate) (PPF) and poly(caprolactone fumarate) (PCLF) to form various hydrogels (FIG.) with controllable hydrophilicity are also disclosed. The hydrogels are useful in the fabrication of injectable and in-situ hardening scaffolds for application in skeletal reconstruction. An injectable material including the hydrogels may be useful in controlled drug release.
