Document Type and Number:
Japanese Patent JP4636759
Kind Code:
B2
Abstract:
New group 11 or 12 compound with a tridentate ligand with multiple uses as a catalyst and initiator and/or chain extender in (co)polymerization can be used to give biodegradable polymers. New group 11 or 12 compound with a tridentate ligand is of formula (I); M = group 11 or 12 element; Rm = H, halogen, (cyclo)alkyl, aryl(oxy), arylthio, (cyclo)alkoxy, (cyclo)alkylthio, amino, (di)alkylamino, (di)cycloalkylamino, alkyl(cycloalkyl)amino, (di)arylamino or (cyclo)alkylarylamino; A, B = 2-4C chain optionally substituted by (cyclo)alkyl or aryl containing halogen, alkyl, NO2 or CN; L1, L2 = E15(R15); E15 = group 15 element; R15 = H, (cyclo)alkyl or aryl optionally substituted by halogen, alkyl, NO2 or CN, group RR'RE14; or SO2Q; E14 = group 14 element; R, R' and R = H, (cyclo)alkyl, aryl(oxy), (cyclo)alkoxy, (cyclo)alkylthio or arylthio, optionally substituted by halogen, alkyl, NO2 or CN; Q = halogen or (halo)alkyl optionally substituted by (halo)alkyl or halogen; L3 = E'15(R'15)(R15) or E16(R16 E'15 = group 15 element; R'15, R15 and R16 = H, (cyclo)alkyl or aryl optionally substituted by halogen, alkyl, NO2 or CN, group TT'TE'14; E16 = group 16 element; E'14 = group 14 element; T, T' and T = H, (cyclo)alkyl, ary(oxy), (cyclo)alkoxy, arylthio or (cyclo)alkylthio, optionally substituted by halogen, alkyl, NO2 or CN, or SO2Q'; and Q' = halogen, (halo)alkyl or aryl optionally substituted by (halo)alkyl or halogen. Independent claims are included for the preparation of the above compounds by reacting compounds of formula (L1AL2BL3)<->Y<+> and MRmZ, the preparation of (co)polymers by reaction at up to 200 degrees C for up to 300 h using the above compound as initiator and/or chain regulator and catalyst and the obtained (co)polymers. Y = H, metal or metallic group; and Z = leaving group.
