Abstract

Procédé de fabrication d'une composition polymère contenant une substance physiologiquement active et ayant pour rôle de libérer la substance active à vitesse contrôlée Le procédé consiste à mettre en contact un ou plusieurs monomères polymérisables et la substance physiologiquement active en leur donnant une forme spécifique et à irradier avec de la lumière ou des radiations ionisantes à basse température inférieures à la température ambiante pour polymériser ces monomères polymérisables. Application en physiologie.
