CA 2528150

Fumaric acid or a salt thereof, such as a fumaryl halide (e.g., fumaryl chloride), which contains unsaturated carbon-carbon double bonds that can be used for in situ crosslinking, is copolymerized with a biodegradable poly(caprolactone) macromer that has a flexible backbone such that the resulting copolymer may self-crosslink in the absence of a crosslinking agent. The biocompatible and bioresorbable poly(caprolactone fumarate) biomaterial is useful in the fabrication of injectable and in-situ hardening scaffolds for application in skeletal reconstruction.

Un acide fumarique ou un de ses sels, tels que l'halogénure de fumaryle (par exemple, le chlorure de fumaryle) contenant des liaisons doubles carbone-carbone insaturées qui peuvent être utilisées pour une réticulation in situ, est copolymérisé avec un macromère de poly(caprolactone) biodégradable présentant un squelette flexible de sorte que le copolymère obtenu est capable de réticulation spontanée en l'absence d'un agent de réticulation. Le matériau biologique de poly(caprolactone fumarate) biocompatible et biorésorbable est utile dans la fabrication de squelettes injectables et durcissables in situ pour utilisation dans la reconstruction osseuse.
