ABSTRACT:
A process for producing polybutadiene essentially consisted of syndiotactic-1,2-polybutadiene in an aqueous medium includes a step off polymerizing diene essentially consisted of 1,3-butadiene in the presence of: (A) a catalyst composition including (a) a transition metal compound, and (b) an organometallic compound which includes a metal selected from the elements consisting off groups 1, 2, 12, and 13 of Periodic Table; (B) an initiator comprising at least one component selected from a group consisting of carbon disulfide, an isothiocyanate compound, and a xanthogenic compound; and (C) an inert organic liquid having a density of at least 1.10, thereby resultant particles of syndiotactic-1,2-polybutadiene have a diameter up to 2 min.
