Abstract
MEZCLA POLIMERICA PARTICULARMENTE UTIL COMO MEJORADOR DEL IV QUE COMPRENDE UN POLIMERO RADIAL ASIMETRICO HIDROGENADO SELECTIVAMENTE CON VARIOS BRAZOS POLIMERICOS QUE CONTIENEN UNIDADES MONOMERICAS DIOLEFINICAS CONJUGADAS HIDROGENADAS Y POR LO MENOS UN BRAZO E COPOLIMERO BLOQUE, Y UN COPOLIMERO DIBLOQUE CON UNIDADES DE HIDROCARBURO AROMATICO MONOBLOQUENILICO Y UNIDADES DE DIOLEFINA CONJUGADA HIDROGENADO SELECTIVAMENTE. LOS DOS POLIMEROS DE LA MEZCLA PUEDEN SER SELECTIVAMENTE HIDROGENADOS PARA SATURAR AL MENOS EL 95% DE LA INSATURACION ETILENICA INICIAL. CUANDO SE EMPLEA LA MEZCLA COMO MEJORADOR DE LA IV, MEJORA LA EFICACIA DE ESPESAMIENTO POR ENCIMA DE LA QUE CABRIA ESPERAR DE LA CONTRIBUCION DE CADA COMPONENTE POR SEPARADO. LOS BLOQUES DE HIDROCARBURO AROMATICO MONOALQUENILICO SON PREFERIBLEMENTE DE ESTIRENO Y LA DIOLEFINA CONJUGADA ES PREFERIBLEMENTE ISOPRENO.
