HYDROXYSTYRENE DIMER DERIVATIVE, METHOD FOR PRODUCING THE SAME, CHAIN-TRANSFER AGENT AND METHOD FOR POLYMERIZING RADICALLY POLYMERIZABLE MONOMER

摘要

PROBLEM TO BE SOLVED: To provide a hydroxystyrene dimer derivative useful as a chain-transfer agent efficiently controlling the molecular weight of a polymer or copolymer obtained by radical polymerization, a method for producing the same, a chain-transfer agent, and a method for polymerizing a radically polymerizable monomer.;SOLUTION: The structure of the hydroxystyrene dimer derivative is represented by formula (1) (wherein substituents R¹ and R³ are each hydrogen, an alkoxy group or an acetoxy group and R² is an acetyl group or an alkyl group).;COPYRIGHT: (C)2011,JPO&INPIT
