Effective catalytic copolymerization of norbornene and norbornene derivatives |
| 초록 |
A series of nickel (II) complexes with hetero atom coordinated ligand were synthesized and characterized by single crystal X-ray diffraction. Nickel complex had differences in electrical properties by changing in functional groups. The homo- and copolymerization of norbornene (NB) and norbornene derivative(NBD) with polar functional group was catalyzed by these nickel complexes. All polymerizations were carried out in toluene with the presence of borane cocatalyst. The high catalytic activity was observed in all Ni complexes (up to 105 g/(Ni mol•.h)) in copolymerization. The copolymers were produced as high yield (up to 90%) with relatively high molecular weight as well as narrow molecular weight distribution and various content of NBD was incorporated in copolymer. The obtained copolymers were confirmed to have a good thermal stability and showed the good solubility in common organic solvents. |
