Abstract

EL TRANS-1,4-POLIBUTADIENO ES UNA RESINA TERMOPLASTICA EN LUGAR DE UN CAUCHO A TEMPERATURA AMBIENTE EN VIRTUD DE SU ALTO GRADO DE CRISTALINIDAD. PUESTO QUE EL TRANS-1,4-POLIBUTADIENO CONTIENE MUCHOS ENLACES DOBLES EN SU BASE, SE PUEDE MEZCLAR Y COCURAR CON CAUCHOS. ES POR TANTO UNA ALTERNATIVA INTERESANTE A LOS RELLENADORES TRADICIONALES COMO POR EJEMPLO NEGRO DE CARBON QUE NORMALMENTE SE UTILIZAN PARA COMPONER CAUCHO. SI SE UTILIZAN EL SISTEMA CATALIZADOR Y LOS METODOS DE LA INVENCION, EL TRANS-1,4-POLIBUTADIENO SE PUEDE SINTETIZAR A UN ALTO NIVEL DE CONVERSION . LA INVENCION SE REFIERE DE MANERA MAS ESPECIFICA A UN PROCESO PARA LA SINTESIS DEL TRANS-1,4-POLIBUTADIENO MEDIANTE UN PROCESO DE POLIMERIZACION ANIONICO QUE CONSISTE EN: (A) AÑADIR UN COMPUESTO DE ORGANOLITIO Y UN ALCOXIDO DE METAL ALCALINO COMO SISTEMA CATALIZADOR A UN MEDIO DE POLIMERIZACION QUE CONTIENE UN MONOMERO DE 1,3-BUTADIENO Y UN SOLVENTE ORGANICO; Y (B) PERMITIR QUE EL MONOMERO DE 1,3-BUTADIENO SE POLIMERICE A UNA TEMPERATURA QUE OSCILA ENTRE UNOS -10 C Y UNOS 45 C PARA PRODUCIR EL TRANS-1,4-POLIBUTADIENO.
