Title:
LIVING POLYMERIZATION INITIATOR AND POLYMERIZATION METHOD USING THE SAME
Document Type and Number:
Japanese Patent JP3614468
Kind Code:
B2
Abstract:
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 CX1X2X3X4 (wherein X1 to X4 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 AlY1Y2Y3 (wherein Y1 to Y3 each is a halogen, an alkyl, an aryl, an alkoxy, or allyloxy) or by MZ1Z2Z3Z4 (wherein M is Ti or Sn and Z1 to Z4 each is a halogen, an alkyl, etc.).
