Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO DE POLIMERIZACION DE OLEFINAS QUE CONSISTE EN PONER EN CONTACTO ETILENO POR SI SOLO O CON UNO O MAS COMONOMEROS NO SATURADOS OLEFINICAMENTE CON UN COMPUESTO CATALIZADOR DE METALOCENO DEL GRUPO 3 - 6 QUE CONTIENE UN ANILLO ENLAZADO A PI QUE TIENE UN SUSTITUYENTE HIDROCARBILO, HIDROCARBILSILILO O HIDROCARBILGERMILO C 3 O SUPERIOR, QUEDANDO DICHO SUSTITUYENTE ENLAZADO AL ANILLO A TRAVES DE UN ATOMO DE CARBONO PRIMARIO; Y CONTENIENDO EL COMPUESTO DOS ANILLOS ENLAZADOS A PI , SIENDO EL NUMERO TOTAL DE SUSTITUYENTES EN LOS ANILLOS IGUAL A UN NUMERO DEL 3 AL 10, SIENDO DICHOS ANILLOS ASIMETRICAMENTE SUSTITUIDOS CUANDO EL NUMERO DE SUSTITUYENTES ES 3 O 4. EL PROCEDIMIENTO DE LA INVENCION ES PARTICULARMENTE ADECUADO PARA LA PREPARACION DE COPOLIMEROS DE ETILENO CON UN MIR INFERIOR A 35 APROXIMADAMENTE, AL TIEMPO QUE SE MANTIENE UNA ESTRECHA CD INCLUSO A ALTOS INDICES DE INCORPORACION DE COMONOMEROS, Y CON CIERTAS REALIZACIONES DE LA INVENCION SE OBTIENEN COPOLIMEROS DE ETILENO CON UNA RESISTENCIA MEJORADA A LA FUSION CON EL MIR BAJO.
