摘要： PROCESS FOR PRODUCING BUTADIENE POLYMER CONTAINING PREDOMINANTLY CIS-1,4 STRUCTURE WHICH COMPRISES POLYMERIZING 1,3-BUTADIENE IN THE PRESENCE OF A CATALYST SYSTEM IN A LIQUID MEDIUM AT A TEMPERATURE OF -30 TO 150*C., THE CATALYST SYSTEM CONSISTING ESSENTIALLY OF (A) AT LEAST ONE OF NICKEL AND COBALT COMPOUNDS, (B) A TRIALKYL ALUMINUM COMPOUND AND (C) AT LEAST ONE MEMBER SELECTED FROM THE GROUP CONSISTING OF (1) THE COMBINATION OF A HYDROQUINONE COMPOUND REPRESENTED BY THE FORMULA:

1,4-DI(HO-),2-R1,3-R2,5-R4,6-R3-BENZENE

(WHEREIN R1, R2, R3 AND R4 ARE INDIVIDUALLY A HYDROGEN ATOM OR A HALOGEN ATOM OR THE COMBINATION OF R1 WITH R2 AND/OR OF R3 WITH R4 MAY REPRESENT AN AROMATIC CONDENSED RING(S) AND THE REMAINING ONES ARE, IF ANY, EACH A HYDROGEN ATOM OR A HALOGEN ATOM) WITH A BENZOTRIFLUORIDE COMPOUND REPRESENTED BY THE FORMULA:

1-CF3,2-R1,3-R2,4-R3,5-R4,6-R5-BENZENE

(WHEREIN R1, R2, R3, R4 AND R5 ARE INDIVIDUALLY A HYDROGEN ATOM, A HALOGEN ATOM, AN ALKYL GROUP OR A FLUOROALKYL GROUP), (2) THE HYDROQUINONE COMPOUND REPRESENTED BY THE FORMULA I, OR (3) A PENTA-HALOGENATED PHENOL COMPOUND REPRESENTED BY THE FORMULA:

1-X1,2-X2,3-X3,4-X4,5-X5,6-HO-BENZENE

(WHEREIN X1, X2, X3, X4 AND X5 ARE INDIVIDUALLY A HALOGEN ATOM).
