Abstract
Soluble catalysts for polymerizations are provided which are formed from an organic polymeric material containing at least one functional group bound to a metal, metal ion or metal complex. These catalysts can be used to promote all types of polymerizations, such as of vinyl compounds, etc. These catalysts are produced by reacting the basic polymer with a metal salt or metal complex, particularly of a metal of the third through the eighth subgroups of the periodic table or of the third and fourth main groups of the periodic table, the catalyst being formed by exchange with the metal or metal ion being bound to the polymer.
