Abstract
Mejoras introducidas en el objeto de la patente principal Nº 438.160 solicitada el 3 de junio de 1975 por: "un procedimiento de polimerización de dienos conjugados", o copolimerización de dienos conjugados con otros dienos conjugados o con compuestos vinil-aromáticos, según las cuales para preparar polímeros o copolímeros que tienen simultáneamente contenidos elevados de encadenamientos trans-1,4 y contenidos pequeños de encadenamientos 1,2, dichas mejoras están caracterizadas porque los monómeros se ponen a reaccionar, en continuo o en discontinuo, en masa o en solución, en un disolvente alifático, cicloalifático o aromático, a una temperatura comprendida entre 20 y 100ºC, en presencia de una composición catalítica constituida por un iniciador de órgano-litio y por un cocatalizador compuesto que comprende un compuesto de bario, de estroncio o de calcio, un compuesto organometálico de los metales de los grupos 2 B ó 3 A de la clasificación periódica de los elementos de la tabla de Mendeloev, y un alcoholato-éter o amina de un metal alcalino.
