CA 2475023

A hydroxyapatite complex includes a hydroxyapatite sintered compact that is chemically bonded to a polymer-based material containing at least one functional group selected form a group consisting of an isocyanate group and an alkoxysilyl group, wherein: the hydroxyapatite sintered compact is reacted with the functional group of the polymer-based material. This arrangement allows manufacturing of a hydroxyapatite complex without a chemical pre-treatment of the hydroxyapatite sintered compact.

La présente invention se rapporte à un composite d'hydroxyapatite qui contient : une base polymère possédant des groupes fonctionnels d'au moins une sorte sélectionnée parmi le groupe constitué de groupes isocyanate et alcoxysilyle ; et un aggloméré d'hydroxyapatite chimiquement lié à la base. Il est possible de produire ce composite en faisant réagir les groupes fonctionnels de la base polymère avec l'aggloméré d'hydroxyapatite. Ainsi, il est possible de produire un composite d'hydroxyapatite sans pré-traitement chimique d'un aggloméré d'hydroxyapatite.
