合成了5-位含偶氮苯功能基团的降冰片烯衍生物,并以双-(β-酮萘胺)镍(II)为主催化剂,三五氟苯硼(B(C6F5)3)为助催化剂,在甲苯中对该单体进行了加成均聚合与共聚合研究；采用FT-IR、1H NMR、13C NMR、UV-Vis、GPC、TGA对合成单体及聚合产物进行了表征。结果表明，合成单体及聚合产物均在300-400nm范围具有较强的光学吸收；共聚物的分子量在4.78×104 g/mol到5.15×104 g/mol之间,均聚物的分子量在6.5×105 g/mol到1.28×106 g/mol之间；聚合产物的热稳定性可达到320 °C以上,且在普通有机溶剂中具有良好的溶解性。

Synthesis and Addition Polymerization of Norbornene Derivative with a Pendent Azobenzene Functional Group

Norbornene derivative with a pendent azobenzene functional group was synthesized and its addition copolymerization and homopolymerization were carried out using the catalytic system of bis-(β-ketonaphthylamino)nickel(II)/B(C6F5)3 in toluene. The chemical structures of the monomer and polymer were confirmed by Fourier transform infrared (FTIR) and Nuclear Magnetic Resonance (1H NMR, 13C NMR) spectra. The monomer and polymer were also characterized by UV-visible absorption spectrum. The results showed that polymers had a broad optical absorption band in the range of 300-400 nm. GPC results showed that the number-average molecular weight (Mn)s of copolymer and homopolymer are 4.78×104g/mol~5.15×104g/mol and 6.5×105g/mol~1.28×106g/mol, respectively. The achieved polymers showed high thermal stability and have good solubility in common organic solvents.
