Method Of Making Poly(Propylene Fumarate-Coethylene Oxide)
US Patent:
5644005, Jul 1, 1997
Filed:
Apr 24, 1996
Appl. No.:
8/637355
Inventors:
Laura J. Suggs - Houston TX
Richard G. Payne - Houston TX
Michael J. Yaszemski - San Antonio TX
Antonios G. Mikos - Houston TX

Assignee:
Rice University - Houston TX
International Classification:
C08F 2000
US Classification:
525444
Abstract:
A biodegradable block copolymer made from the transesterfication of a poly(propylene fumarate) prepolymer and a poly(ethylene oxide) prepolymer. The block copolymer poly(propylene fumarate -co- ethylene oxide) is capable of crosslinking at body temperature. Crosslinking requires an appropriate crosslinking monomer and an initiator. The biodegradable block copolymer has utility as a vascular implant became it can be injected as a fluid into the vascular system and crosslinked in situ.

Filed:
Apr 28, 1994
Appl. No.:

International Classification:
C08G 6302, C08K 332, A61F 200
US Classification:
523116
Abstract:
A novel pathway for the synthesis of poly(propylene fumarate) includes first producing bis-hydroxypropyl fumarate and then its transesterification into poly(propylene fumarate). This synthetic pathway permits production of high molecular weight poly(propylene fumarate) and enables the production of a composite material useful in orthopedic procedures.
