Abstract

UN CAUCHO DE HOMOPOLIMERO ISOOLEFINICO C 4 A C 7 QUE NO POSEE SUSTANCIALMENTE GEL, CAUCHO DE COPOLIMERO DE BUTILO, CAUCHO DE BUTILO HALOGENADO (EJ. CLORADO O BROMADO) O MEZCLAS DE LOS MISMOS, QUE CONTIENEN UNA DISTRIBUCION DEL PESO MOLECULAR TAL QUE LA RELACION DE LOS MOMENTOS DE DICHA DISTRIBUCION DEL PESO MOLECULAR, MZ/MW, ES IGUAL A O SOBREPASA 2,0, Y ESA PORCION DE DICHA DISTRIBUCION DEL PESO MOLECULAR QUE ES IGUAL O SUPERIOR A 4 VECES EL PESO MOLECULAR MAXIMO, MP, CONTIENE MAS DE UN 8 POR CIENTO DEL TOTAL DE LAS ESPECIES POLIMERICAS Y MP ES SUPERIOR A 250.000 Y EN DONDE DICHAS ESPECIES POLIMERICAS CON UN PESO MOLECULAR INFERIOR AL MP NO TIENEN SUSTANCIALMENTE RAMIFICACIONES. SE PRESENTAN VARIOS MEDIOS PARA LLEVAR A CABO LA DISTRIBUCION DEL PESO MOLECULAR INCLUIDA LA MEZCLA DE HOMOPOLIMEROS Y/O COPOLIMEROS CON UN PESO MOLECULAR Y UNA DISTRIBUCION DEL PESO MOLECULAR APROPIADOS Y UNA POLIMERIZACION DIRECTA UTILIZANDO UN REACTIVO FUNCIONAL PARA INTRODUCIR UNA RAMIFICACION. LAS COMPOSICIONES DE CAUCHO SON PARTICULARMENTE UTILES EN APLICACIONES EN LAS QUE SE UTILIZA CAUCHO DE BUTILO O CAUCHO DE BUTILO HALOGENADO Y CUANDO SE DESEA OBTENER UNA GRAN RESISTENCIA AL VERDE EN COMBINACION CON UNA MAYOR VELOCIDAD DE RELAJACION DE ESFUERZOS. TALES POLIMEROS SON PARTICULARMENTE ADECUADOS PARA SU USO EN COMPOSICIONES PARA EL REVESTIMIENTO INTERIOR DE NEUMATICOS.
