Zusammenfassung:	PARA LALIBERACION CONTROLADA DE UN INGREDIENTE ACTIVO SE HAN PROVISTO VEHICULOS DE LIBERACION CONSISTENTES EN UN GLOBULO DE POLIMERO DE UNA RED DE POROS CON UN INGREDIENTE ACTIVO CONTENIDO DE DICHA RED. LA RED DE POROS ES USTANCIALMENTE NO COLAPSABLE CON LA EXTRACCION DEL INGREDIENTE ACTIVO Y LOSVEHICULOS DE LIBREACION ESTAN POLIMERIZADOS POR UN PROCESO EN ELCUAL EL INGREDIENTE ACTIVO COMPRENDE TAMBIEN ELPOROGENO DURANTE LA FORMACION DE LA RED DE POROS. Delivery vehicles comprised of a polymeric bead having a network of pores with an active ingredient held within the network are provided for use in a method to provide controlled release of the active ingredient. The network of pores is substantially non-collapsible upon removal of the active ingredient and the delivery vehicles are polymerized by a process in which the active ingredient also comprises the porogen during formation of the network of pores.
