Claim 1
Independent Claim
150 words
A METHOD FOR POLYMERIZING A MONOMERIC MATERIAL COMPRISING A CONJUGATED DIENE CONTAINING FROM 4 TO 8, INCLUSIVE, CARBON ATOMS TO NORMALLY SOLID POLYMER WHICH COMPRISES CONTACTING SAID MONOMERIC MATERIAL WITH A CATALYST SYSTEM COMPRISING (A) A HALIDE OF A GROUP IV METAL CONTAINING FROM 2 TO 4, INCLUSIVE, HALOGEN ATOMS AND (B) AN ORGANO METAL HAVING THE FORMULA MRN WHERE M IS A METAL SELECTED FROM THE GROUP CONSISTING OF ALUMINUM, GALLIUM, INDIUM, THALLIUM AND BERYLLIUM, EACH R IS SELECTED FROM THE GROUP CONSISTING OF SATURATED ACYCLIC HYDROCARBON RADICALS, SATURATED CYCLIC HYDROCARBON RADICALS, AND AROMATIC HYDROCARBON RADICALS, AND N IS AN INTEGER EQUALING THE VALENCE OF M, AT A TEMPERATURE IN THE RANGE OF -100 DEGREES C. IN THE PRESENCE OF AN INERT DILUENT WHICH IS LIQUID UNDER THE REACTION CONDITIONS AND A PROMOTING AMOUNT OF A POLYNUCLEAR AROMATIC HYDROCARBON HAVING THE GENERAL FORMULA SELECTED FROM THE GROUP CONSISTING OF:
