Abstract:
A polymerization catalyst composition for a radically polymerizable monomer of the present invention comprises a transition metal-containing phosphazenium composition which is produced by mixing a phosphazenium compound with a compound of a transition metal belonging to Groups 4 to 12 in the periodic table and an organic halogen compound.
