Abstract

Procedimiento de preparación de un sustrato hidrófobo apto para liberar una sustancia química, caracterizado porque consiste en: a) formar en un polvo de polímero hidrófobo, inclusiones de compuestos polimerizados, injertando sobre el polvo de polímero hidrófobo un monómero de naturaleza diferente de la de dicho polímero hidrófobo, b) mezclar de manera homogénea el polvo injertado así obtenido, con un polvo de dicha sustancia, y c) dar a la mezcla la forma de un sustrato, sometiéndola a una conformación en caliente.
