Abstract

Microcápsulas con recubrimientos poliméricos que poseen grupos bloqueantes (por ejemplo, grupos bloqueantes de aminas), cuya eliminacion o clivaje inicia la liberacion del material contenido en el nucleo de las mismas o incrementa la velocidad a la cual es liberado dicho material del nucleo. La presente está dirigida además a la formulacion de dichas microcápsulas en dispersiones acuosas, a la preparacion de dichas microcápsulas y al uso de dichas microcápsulas y de las dispersiones de las mismas. Reivindicacion 1: Una microcápsula, caracterizada porque comprende: un material en el nucleo sustancialmente inmiscible en agua que comprende un compuesto biologicamente activo; y una pared de recubrimiento que encapsula el material del nucleo; donde dicha pared de recubrimiento se forma por una polimerizacion interfacial de un monomero de isocianato con un monomero de amina en un encapsulamiento por polimerizacion formadora del recubrimiento, y donde el esqueleto polimérico de dicha pared de recubrimiento comprende una unidad repetida que contiene nitrogeno y al menos un grupo bloqueante, donde la ruptura de un enlace con dicho grupo bloqueante es eficaz para incrementar la velocidad a la cual la microcápsula libera dicho compuesto biologicamente activo.
