Abstract

Se dan a conocer poblaciones de partículas de administración de agentes beneficiosos, las partículas tienen un núcleo y una pared polimérica que rodea el núcleo, la pared polimérica comprende polímeros multifuncionales a base de (met)acrilato, junto con procesos de fabricación y usos de dichas composiciones, y artículos fabricados con dichas partículas. La pared polimérica comprende un polímero de (met)acrilato derivado, al menos en parte, de monómeros de pared y al menos un iniciador de radicales libres, en donde los monómeros de pared comprenden al menos un 50%, en peso de los monómeros de pared, de monómeros de (met)acrilato, en donde el al menos un iniciador de radicales libres está presente a un nivel de entre alrededor de un 15% y alrededor de un 60%, en peso de la pared polimérica, en donde el núcleo comprende un agente beneficioso, en donde el núcleo y la pared polimérica están presentes en una proporción en peso de entre alrededor de 95:5 y alrededor de 99.5:0.5. Las composiciones proporcionan el contenido del núcleo con un perfil de suministro deseado.
