Tellurium-containing compound and method of producing polymer

A method of producing a polymer, the method comprising polymerizing a compound having a carbon-carbon double bond in the presence of at least one compound selected from the group consisting of the compounds represented by the following Formulae (1) to (4):

• wherein, in Formulae (1) to (4),
• R1 represents an unsubstituted alkyl group having from 2 to 6 carbon atoms,
• each of R2 and R3 independently represents a hydrogen atom, or a substituted or unsubstituted alkyl group having from 1 to 6 carbon atoms,
• Ar represents a substituted or unsubstituted aryl group having an aromatic ring composed of from 5 to 18 atoms,
• Rf represents a perfluoroalkyl group having from 1 to 12 carbon atoms,
• A represents a substituted or unsubstituted alkyl group having from 1 to 12 carbon atoms, or a substituted or unsubstituted aryl group having an aromatic ring composed of from 5 to 18 atoms,
• X represents a hydrogen atom, a fluorine atom, a CF2—Z group, or a CHF—Z group,
• Y represents a CF2—Z group or a CHF—Z group, and
• Z represents a fluorine atom or an organic group having from 1 to 12 carbon atoms, and
• in Formulae (2) and (3), Y and Rf are or are not linked to each other to form a cyclic structure.
