multifunctional polyurethane matrix monopolym\u00e9rique cast block is obtained in a simple and efficient manner.down sequentially in a mold in different solutions of isocyanate polyol phase alternating on \/ complex solutions of said phase in order in accordance with the agreement, and the stage of the polymerization, after the pot life and before the time of d\u00e9mou lage) sequence before being cast.to complete the casting of the solution phase is up to its release time and thus to complete the polymerization of the matrix. it is responsible for the \"reservoir\" in the active sequences of natural or synthetic origin, import patches or volatile.these are substances and therapeutic, cosmetic, health and welfare, repellents, attractants, pheromone, biocides, perfumes and deodorants. two or more assets can be loaded in the same matrix to move unidirectionally or in opposite directions.the matrix is used in the forming of various devices that adhere to the skin or other surface, to provide one or more substances in a controlled manner.these devices are patches, patches with more assets, glued on patches of exchangeable base fabric, shoes and shoe pads for bearing assets, for the control of insect pheromone, attractive insecticid self-adhesive pads es, or other equivalent devices in terms of structure and function.Une matrice séquencée multifonctionnelle monopolymérique en polyuréthanne coulé est obtenue de manière simple et efficace, en coulant séquentiellement dans un moule successivement différentes solutions de phase disocyanate/complexe polyol avec alternance d Objectivation desdites solutions de phase selon un ordre convenu et dans le respect du stade de la polymérisation (après le pot life et avant le temps de démoulage) de la séquence précédant celle en cours de coulage, pour clôturer par le coulage de la dernière solution de phase qui va aller jusquà son temps de démoulage et achever ainsi la polymérisation de lensemble de la matrice. Elle est chargée dans s
