Abstract

EL PRESENTE INVENTO SE DIRIGE A NUEVOS POLIMEROS DE BLOQUE ELASTOMERICOS, POLIMODALES Y A UNA CINTA ADHESIVA PIEZOSENSIBLE ELABORADA A PARTIR DE ELLOS. EL NUEVO COPOLIMERO DE BLOQUE COMPRENDE DE 4 A 40 POR CIENTO DEL PESO DE UN COMPUESTO AROMATICO DE MONOVINILO POLIMERIZADO Y DE ALREDEDOR DEL 96 A ALREDEDOR EL 60 POR CIENTO DEL PESO DE UN DIENO CONJUGADO. EL COPOLIMERO DE BLOQUE TIENE LA FORMULA GENERAL Q{SUB,N}Y DONDE Q REPRESENTA UN BRAZO INDIVIDUAL DEL COPOLIMERO DE BLOQUE Y TIENE LA FORMULA S-B; N REPRESENTA EL NUMERO DE BRAZOS Y ES AL MENOS 3; Y Y ES EL RESIDUO DE UN AGENTE DE CONEXION MULTIFUNCIONAL. ADEMAS, S ES UN EXTREMO DE BLOQUE DEL SEGMENTO POLIMERO NO ELASTOMERICO DE UN HOMOPOLIMERO AROMATICO MONOVINILO POLIMERIZADO, EXISTIENDO AL MENOS DOS EXTREMOS DE BLOQUE DE PESO MOLECULAR DIFERENTE EN EL COPOLIMERO DE BLOQUE. EL NUMERO DEL PESO MOLECULAR MEDIO DEL EXTREMO DE BLOQUE DE PESO MOLECULAR MAS ALTO (MN){SUB,H} SE ENCUENTRA EN EL INTERVALO DE ALREDEDOR DE 5.000 A ALREDEDOR DE 50.000, Y EL NUMERO DEL PESO MOLECULAR MEDIO DEL EXTREMO DE BLOQUE DE PESO MOLECULAR INFERIOR (MN){SUB,L} SE ENCUENTRA EN EL INTERVALO DE ALREDEDOR DE 2.000 A ALREDEDOR 10.000. EL COEFICIENTE (MN){SUB,H}/(MN){SUB,L} ES DE AL MENOS 1,25. ADEMAS, B ES UN BLOQUE CENTRAL DEL SEGMENTO POLIMERO ELASTOMERICO QUE CONECTA CADA BRAZO A UN RESIDUO DE UN AGENTE DE ENLACE MULTIFUNCIOANL (Y), Y COMPRENDE UN DIENO CONJUGADO POLIMERIZADO O UNA COMBINACION DE DIENOS CONJUGADOS.
