Abstract

LA INVENCION SE REFIERE A UN TECNICA DE POLIMERIZACION ANIONICA PARA SINTETIZAR POLIMEROS DE CAUCHO DE MONOMEROS DE DIOLEFINAS CONJUGADAS, COMO UN COPOLIMERO DE CAUCHO DE {AL}-METILESTIRENO Y 1,3-BUTADIENO. ESTOS COPOLIMEROS DE CAUCHO MUESTRAN UNA EXCELENTE COMBINACION DE PROPIEDADES PARA LA UTILIZACION EN COMPUESTOS DE CAUCHO NEUMATICOS. TIENEN ALTOS CONTENIDOS DE TRANS ISOMEROS QUE CONDUCEN A UNAS BUENAS CARACTERISTICAS DE LA BANDA DE RODADURA Y A UNA DISTRIBUCION DE PESO MOLECULAR ANCHA CON UNA PROCESABILIDAD AUMENTADA. ESTA INVENCION MAS ESPECIFICAMENTE DESCRIBE UN PROCESO PARA LA SINTESIS DE POLIMEROS DE CAUCHO CON UNA DISTRIBUCION DE PESO MOLECULAR ANCHA Y QUE SON PARTICULARMENTE UTILES EN COMPUESTOS DE CAUCHO PARA LA BANDA DE RODADURA DE LOS NEUMATICOS, DICHO PROCESO COMPRENDE LA POLIMERIZACION DE AL MENOS UN MONOMERO DIOLEFINICO CONJUGADO EN UN SOLVENTE ORGANICO EN LA PRESENCIA DE UN SISTEMA CATALIZADOR QUE COMPRENDE (A) UN COMPUESTO DE DIALQUILMAGNESIO Y (B) UN METAL ALCALINO CONTENIENDO UN COMPUESTO SELECCIONADO DEL GRUPO CONSISTENTE EN ALCOXIDOS DE METAL ALCALINO, FENOXIDOS DE METAL ALCALINO, SULFOXIDOS DE METAL ALCALINO, SULFONATOS DE METAL ALCALINO, CARBOXILATOS DE METAL ALCALINO, FENOXIDOS DE METAL ALCALINO SUSTITUIDO POR ALQUILO, ALQUILAMINAS DE METAL ALCALINO Y DIALQUILAMINAS DE METAL ALCALINO; EN DONDE LA RELACION MOLAR DEL COMPUESTO CONTENIENDO EL METAL ALCALINO CON EL COMPUESTO DE DIALQUILMAGNESIO ESTA EN EL RANGO DE 6:1 A 1:5. EN CASOS DONDE LOS COPOLIMEROS DE CAUCHO CONTENIENDO {AL}-METILESTIRENO ESTAN SIENDO SINTETIZADO EL METAL ALCALINO EN EL COMPUESTO CONTENIENDO EL METAL ALCALINO PODRIA NORMALMENTE SER POTASIO, RUBIDIO O CESIO, SIENDO CESIO EL MAS PREFERIDO.
