A method for producing a polymer having a group represented by (R 5)(R 6)C=C(R 4)-C(R 2)(R 3)- that is derived from the organotellurium compound represented by the formula which forms one of the terminals of the polymer chain, wherein R 1, R 2 R 3, R 4 and R 5 represent the same meaning as defined in the formula, wherein the polymer is obtained by a method comprising subjecting a radically polymerizable monomer to radical polymerization in a state in which the radical polymerization initiator comprising an organotellurium compound represented by a formula is present in a polymerization system, wherein R 1 represents a group selected from an alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted aryl group, and a substituted or unsubstituted heteroaromatic ring group, each of R 2 and R 3 independently represents an atom or a group selected from a hydrogen atom, an aliphatic hydrocarbon group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heteroaromatic ring group, a halogen atom, a carboxyl group, a hydrocarbyloxycarbonyl group, a cyano group, and an amide group, and each of R 4, R 5, and R 6 independently represents an atom or a group selected from a hydrogen atom, an aliphatic hydrocarbon group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heteroaromatic ring group, a halogen atom, a carboxyl group, a hydrocarbyloxycarbonyl group, a cyano group, an amide group, and a group represented by a formula, provided that two groups selected from R 2 to R 6 are optionally bonded to each other to form a ring other than an aromatic ring, wherein R 7 represents a group selected from an alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted aryl group, and a substituted or unsubstituted heteroaromatic ring group, each of R 8 and R 9 independently represents an atom or a group selected from a hydrogen atom, an aliphatic hydrocarbon group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heteroaromatic ring group, a halogen atom, a carboxyl group, a hydrocarbyloxycarbonyl group, a cyano group, and an amide group, and the wavy line represents that the group represented by the formula is bonded to the carbon atom included in the formula that forms the double bond. wherein R 1 represents a group selected from an alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted aryl group, and a substituted or unsubstituted heteroaromatic ring group, each of R 2 and R 3 independently represents an atom or a group selected from a hydrogen atom, an aliphatic hydrocarbon group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heteroaromatic ring group, a halogen atom, a carboxyl group, a hydrocarbyloxycarbonyl group, a cyano group, and an amide group, and each of R 4, R 5, and R 6 independently represents an atom or a group selected from a hydrogen atom, an aliphatic hydrocarbon group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heteroaromatic ring group, a halogen atom, a carboxyl group, a hydrocarbyloxycarbonyl group, a cyano group, an amide group, and a group represented by a formula, provided that two groups selected from R 2 to R 6 are optionally bonded to each other to form a ring other than an aromatic ring, wherein R 7 represents a group selected from an alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted aryl group, and a substituted or unsubstituted heteroaromatic ring group, each of R 8 and R 9 independently represents an atom or a group selected from a hydrogen atom, an aliphatic hydrocarbon group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heteroaromatic ring group, a halogen atom, a carboxyl group, a hydrocarbyloxycarbonyl group, a cyano group, and an amide group, and the wavy line represents that the group represented by the formula is bonded to the carbon atom included in the formula that forms the double bond.
