    摘要: Poly(propylene fumarate) is copolymerized with poly(caprolactone) diol to produce a block copolymer of poly(propylene fumarate) and poly(caprolactone). The biocompatible and bioresorbable block copolymer of poly(propylene fumarate) and poly(caprolactone) is useful in the fabrication of injectable and in-situ hardening scaffolds for tissue and/or skeletal reconstruction. The block copolymer can be crosslinked by redox or photo-initiation, with or without an additional crosslinker. Thus, the copolymer is both self-crosslinkable (without the use of any crosslinkers) and photocrosslinkable (in the presence of photons such as UV light).

    摘要: 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. 1) 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.
