Controlled/living radical polymerization: Features, developments, and perspectives

Current status and future perspectives in atom transfer radical polymerization (ATRP) are presented. Special emphasis is placed on mechanistic understanding of ATRP, recent synthetic and process development, and new controlled polymer architectures enabled by ATRP. New hybrid materials based on organic/inorganic systems and natural/synthetic polymers are presented. Some current and forthcoming applications are described.

PURPOSE:To obtain an initiator with which a living polymer having a high mol.wt. and a narrow mol.wt. distribution can be easily obtained by using a specific initiator and an activator comprising a combination of a metal complex and a Lewis acid. CONSTITUTION:The initiator comprises a combination of an initiator consisting of a halogenated hydrocarbon represented by CX X X X (wherein X to X may be the same or different, and at least one of them is Cl, Br, or I and the remainder is (are) H or a 1-5C alkyl) or a sulfonyl halide represented by RSO2X (wherein R is a hydrocarbon group optionally substituted with a halogen and X is CI, Br, or I) and an activator consisting of a combination of a complex containing a Group VIII metal of the Periodic Table as the central metal and a Lewis acid represented by AlY Y Y (wherein Y to Y each is a halogen, an alkyl, an aryl, an alkoxy, or allyloxy) or by MZ Z Z Z (wherein M is Ti or Sn and Z to Z each is a halogen, an alkyl, etc.).

PROBLEM TO BE SOLVED: To provide a living polymerization process in which a molecular weight is controlled and a polymer having a narrow molecular weight distribution can be obtained by a living polymerization of a vinyl compound. SOLUTION: In this polymerization process, an unsaturated carboxylic acid or its derivative is polymerized in the presence of a living polymerization initiator comprising (A) an initiator consisting of a predetermined halogenated hydrocarbon or a halogenated sulfonyl compound and (B) an activator consisting of (B1) a metal complex whose central metal is an element of the group VIII in the periodic table and (B2) a predetermined Lewis acid.
