ORGANIC TELLURIUM COMPOUND, PROCESS FOR PRODUCING THE SAME, LIVING RADICAL POLYMERIZATION INITIATOR, PROCESS FOR PRODUCING POLYMER WITH THE SAME, AND POLYMER

摘要

An organotellurium compound represented by the formula (1), which is useful as a living radical polymerization initiator and enables the precise control of molecular weight and molecular-weight distribution under mild conditions. (1) (In the formula, R<1> represents C1-8 alkyl; R<2> and R<3> each represents hydrogen or C1-8 alkyl; and R<4> represents aryl, substituted aryl, an aromatic heterocyclic group, hydroxycarbonyl, or cyano.)
