Abstract
MATRIZ PARA LA LIBERACION DE INGREDIENTES ACTIVOS. LA PRESENTE INVENCION PROPORCIONA UNA MATRIZ PAFRA LIBERAR SUSTANCIAS ACTIVAS, TALES COMO FRAGANCIAS Y FEROMONAS, A LA ATMOSFERA. DICHA MATRIZ ES PERMEABLE A LAS SUSTANCIAS ACTIVAS (INCLUYENDO LAS SUSTANCIAS HIDROFILICAS) Y ESTA HECHA DE UN COPOLIMERO QUE PUEDE REBLANDECERSE LO SUFICIENTE A UNA TEMPERATURA COMPRENDIDA ENTRE 45GC Y 160GC PARA INCORPORAR EN ELLA LAS SUSTANCIAS, SIN RESULTAR DAÑADAS POR LA ACCION DEL CALOR O DE LAS REACCIONES QUIMICAS. DICHA MATRIZ ESTA FORMADA POR UN COPOLIMERO DE BLOQUE, SUSTANCIALMENTE LINEAL, QUE ES EL PRODUCTO DE REACCION DE UN POLIDIORGANOSILOXANO QUE FORMA SEGMENTOS BLANDOS EN DICHO PRODUCTO DE REACCION Y UN DIISOCIANATO QUE FORMA SEGMENTOS DUROS. DICHO COPOLIMRO TIENE UNA TEMPERATURA DE TRANSICION AL VIDRIO ENTRE 45GC Y 160GC, LOS SEGMENTOS BLANDOS CONSTITUYEN DEL 70 AL 99% EN PESO, CON RESPECTO AL PESO DE DICHO COPOLIMERO, Y EL PESO MOLECULAR PROMEDIO DEL COPOLIMERO ENTRE 15.000 Y 500.000.
