Abstract

Procedimiento para la obtención de un catalizador para la polimerización de butadieno , caracterizado porque en secuencia arbitraria a temperaturas entre -70º y +80ºC se hacen reaccionar entre sí a) un compuesto de cobalto, b) un compuesto orgánico de aluminio, c) agua y d) un fosfito de fórmula (I) **fórmula** donde R significa un resto C3-C20-alquilon y R1 significa hidrógeno o un resto C-C6-alquilo.
