Title:
HYPERBRANCHED POLYMER AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2008/029688
Kind Code:
A1
Abstract:
Disclosed is a novel optically stable hyperbranched polymer whose molecular terminal can be derivatized with various compounds. Also disclosed is a method for producing such a polymer. Specifically disclosed is a hyperbranched polymer having a structure represented by the formula (1) below, wherein a halogen atom is at a molecular terminal. The hyperbranched polymer can be obtained by substituting the molecular terminal dithiocarbamate group of a hyperbranched polymer having a dithiocarbamate group at a molecular terminal, which is obtained by living radical polymerization of a dithiocarbamate compound having a vinyl group structure, with a halogen atom. Also disclosed is a hyperbranched polymer wherein an amino group or an ammonium group is at a molecular terminal instead of a halogen atom.
