摘要

合成了5-位含偶氮苯功能基团的降冰片烯衍生物,并采用双-(β-酮萘胺)镍(Ⅱ)/B(C6F5)3催化剂体系在甲苯中对该单体进行了加成均聚合与共聚合,利用FT-IR、1HNMR、13C NMR、UV-Vis、GPC、TGA、DSC对合成的极性单体及聚合物进行了表征.结果表明:该单体及聚合物在300~400 nm范围均有较强的光学吸收;共聚物相对分子质量在4.78×104~5.15×104之间,均聚物相对分子质量在6.5×105~1.28×106之间;烷基链的引入使聚合物的玻璃化温度降低至在573K以下;两种聚合物的热稳定性良好,热分解温度在593K以上;共聚物的溶解性优于均聚物.

Abstract

Norbornene derivative with a functional group of pendent azobenzene was synthesized and the addition copolymerization and homopolymerization of the product were carried out using the catalytic system of bis-(β-keto-naphthylamino)nickel(II)/B(C6F5)3 in toluene.Then,the polar monomer and the polymers were characterized by means of IR,1H NMR,13C NMR,UV,GPC,TGA and DSC.The results show that the polar monomer and the polymers all exhibit broad optical absorption in the range from 300 to 400nm,that the relative molecular mass of the copolymer and the homopolymer are respectively 4.78×104 ~5.15×104 and 6.5×105~1.28×106,that the introduction of alkyl chain decreases the glass transition temperature of the polymers to less than 573K,that the polymers are of strong thermal stability and the thermal decomposition temperature is up to 593K,and that the solubility of the copolymer is better than that of the homopolymer.
