ORGANIC TELLURIUM COMPOUND, METHOD FOR PRODUCING SAME, LIVING RADICAL POLYMERIZATION INITIATOR, METHOD FOR PRODUCING VINYL POLYMER, AND VINYL POLYMER

摘要

An organic tellurium compound is disclosed having a versatility that, when used as a living radical polymerization initiator, it is applicable to polymerization of a vinyl monomer in an aqueous vehicle without using any surfactant or dispersant. The organic tellurium compound is represented by a general formula (1),; ;where R¹ and R² each independently represent a hydrogen atom or an alkyl group having 1 to 8 carbon atoms, A represents an alkali metal atom or an alkaline earth metal atom, x=1 when A is monovalent, x=½ when A is divalent, and R³ is represented by a general formula (2),; ;where in the general formula (2) R⁴ represents a hydrogen atom or an alkyl group having 1 to 8 carbon atoms, R⁵ and R⁶ each independently represent an alkylene group having 2 to 8 carbon atoms, and a represents an integer from 0 to 10.
