Document Type and Number:
Japanese Patent JPH04198303
Kind Code:
A
Abstract:
PURPOSE:To provide a radical polymerization initiator expressed by a specific formula, having living radical polymerization initiation performance, giving a polymer having high molecular weight and narrow molecular weight distribution and useful for the production of a polymer containing various functional groups introduced to the terminals. CONSTITUTION:The objective polymerization initiator is expressed by formula [R<1> is (substituted) aliphatic hydrocarbon group, (substituted) alicyclic hydrocarbon group or (substituted) aromatic hydrocarbon group; R<2> to R<4> are (substituted) aromatic hydrocarbon group].
