Abstract
Metallocene that is polymerizable by free radical catalysis and has metal nucleus in a state of oxidation below its maximum can be polymerized without oxidation of such nucleus by forming a reaction mixture containing said metallocene and the reducing agent of a redox catalyst combination, then initiating and maintaining polymerization of said metallocene with the gradual addition of the oxidizing agent of said combination to said reaction mixture.
Claims5
In a process for the polymerization of a metallocene compound that is polymerizable by free radical polymerization and has a metal nucleus in a state of oxidation below maximum, the improvement for suppressing oxidation of the metal nucleus of said metallocene which comprises:
- forming a reaction mixture containing said metallocene and the reducing agent of a redox catalyst combination;
- then initiating and maintaining polymerization of said metallocene with the gradual addition of the oxidizing agent of said combination to said reaction mixture.
