Abstract

SE DESCRIBE UN NEUMATICO QUE TIENE UNA LLANTA DE UNA COMPOSICION DE CAUCHO PRODUCIDO POR LA MEZCLA DE UN COMPONENTE DE CAUCHO CON UN ELASTOMERO TERMOPLASTICO EN BASE ESTIRENO, EL COMPONENTE DE CAUCHO ESTA COMPUESTO DE UN CAUCHO CON BASE DIENO Y EL ELASTOMERO ESTA CRUZADO INTERNAMENTE CON UNA TENSION TENSIL A 100% DE ELONGACION INCREMENTADA DE 10 AL 1.000% DE TAL MANERA QUE EL ELASTOMERO TERMOPLASTICO NO ESTA INTERNAMENTE CRUZADO. SE DESCRIBE TAMBIEN UN NEUMATICO QUE TIENE UNA LLANTA COMPUESTA DE UN CAUCHO MEZCLADO CON UN ELASTOMERO TERMOPLASTICO HIDROCARBURO AROMATICO EN UNA PROPORCION DEL 5 AL 80 PARTES POR PESO EN RELACION A 100 PARTES POR PESO DEL COMPONENTE DE CAUCHO, EL ELASTOMERO TERMOPLASTICO SATISFACE LOS SIGUIENTES REQUERIMIENTOS: (1) EL ELASTOMERO ES UN HIDROCARBURO AROMATICO DE VINILO CONJUGADO CON BASE DIENO, ELASTOMERO TERMOPLASTICO TIPO BLOQUE; (2) EL ELASTOMERO TIENE UNA RELACION EN PESO ENTRE EL HIDROCARBURO AROMATICO Y EL DIENO CONJUGADO COMO UNIDADES MONOMERO DE 40/60 A 95/5; (3) EL CONTENIDO DEL HIDROCARBURO AROMATICO VINILO EN LOS SEGMENTOS DEL HIDROCARBURO AROMATICO EN EL ELASTOMERO NO ES MENOR QUE 50% POR PESO; Y (4) EL PESO PROMEDIO DEL PESO MOLECULAR DEL ELASTOMERO NO ES MENOR QUE 1 X 10 ELEVADO 5.
