Claim 8:
9. The process according to claim 1, characterized in that
the first component is used in an amount such that a target concentration of the component, based on the mass of the final polymer, is about 10-1000;
the second component is used in an amount such that a target concentration of the component, based on the mass of the final polymer, is about 0.2-50;
the third component is used in an amount such that a target concentration of the component, based on the mass of the final polymer and the alkali metal, is about 0.005-2; and
the fourth component-is used in such an amount that the amount of the component is about 1.1-3 times the molar ratio based on the amount of the third component of the catalyst system used,
or
characterized in that
the first component is used in an amount such that a target concentration of the component, based on the mass of the final polymer, is about 10-1000;
the second component is used in an amount such that a target concentration of the component, based on the mass of the final polymer, is about 0.2-50;
the third component is used in an amount such that a target concentration of the component, based on the mass of the final polymer and the alkali metal, is about 0.005-2 ppm; and
the fourth component is used in an amount such that the amount of the component is about 1.1-3 times the molar ratio based on the amount of the third component of the catalyst system used.
