摘要：
WHEREIN AT LEAST TWO OF R1, R2, R3 and R4 are selected from halogen atoms of same or different kind of cyano groups and others are each hydrogen, halogen or cyano, or the combinations of R1 with R2 and/or of R3 and with R4 may represent an aromatic condensed ring(s) and the remaining ones are, if any, each hydrogen, halogen or cyano in a liquid medium at a temperature from -30* to 150*C.
Process for production of butadiene polymer containing predominantly cis-1,4 structure which comprises polymerizing butadiene in the presence of a catalyst system consisting essentially of (1) at least one of nickel and cobalt compounds, (2) trialkyl aluminum and (3) at least one of the benzoquinone compounds represented by either one of the formulas:
