Se describen un polímero arrastrado o una composición de polímero arrastrado, y un método para formar y adherir una estructura de polímero arrastrado a un sustrato utilizando el polímero arrastrado o una composición de polímero arrastrado. El método incluye proporcionar un sustrato configurado para recibir la aplicación de un polímero arrastrado fundido. Un polímero arrastrado en partículas en forma fundida se aplica en una forma predeterminada, a una superficie del sustrato, para formar una estructura de polímero arrastrado solidificado sobre el sustrato. El polímero arrastrado incluye un material monolítico formado por al menos un polímero base y un agente activo en partículas. La superficie del sustrato es compatible con el polímero arrastrado fundido para unirse térmicamente con él. De esta manera, el polímero arrastrado se une al sustrato y solidifica con suficiente enfriamiento del polímero arrastrado
