Photoactivatable prepolymers and methods of use thereof are disclosed for microencapsulation of a substantially water-insoluble material within a nonporous shell. As provided herein, the microencapsulated material is released with no more than a slow release rate. Upon exposure of the nonporous shell to light, the nonporous shell is converted into a porous shell having an increased release rate for the microencapsulated material.
L'invention concerne des prépolymères photoactivables et des procédés d'utilisation de ceux-ci, destinés à la micro-encapsulation d'un matériau, essentiellement insoluble dans l'eau, dans une enveloppe non poreuse. Ledit matériau micro-encapsulé est uniquement libéré à une faible vitesse de libération. Lors de l'exposition de l'enveloppe non poreuse à la lumière, celle-ci est convertie en une enveloppe poreuse présentant une vitesse de libération augmentée du matériau micro-encapsulé.
