合成了不同邻菲啰啉(phen)含量的聚(苯乙烯-丙烯酸)载体铁邻菲啰啉配合物(SAAC·Fe·phen)和不同5-硝基邻菲啰啉(Nphen)含量的聚(苯乙烯-丙烯酸)载体铁5-硝基邻菲啰啉配合物(SAAC·Fe·Nphen)。元素分析和红外结果证明SAAC·Fe·phen具有下面的结构:SAAC·Fe·phen-(i-Bu)_3Al二元体系的催化效率是SAAC·Fe-phen-(i-Bu)_3Al三元体系的2倍,是小分子铁的400倍。在SAAC·Fe·phen和SAAC·Fe·Nphen体系中,当phen(或N pnen)/Fe的摩尔比为0.7左右时催化活性最高。催化活性随着Al/Fe摩尔比的增大而升高,但当Al/Fe摩尔比大于70以上活性趋于恒定,和小分子铁催化荆相比这种高分子铁催化剂可以提高聚合温度。
The poly (styrene-acrylic acid) iron-phenanthroline complexes (SAAC · Fe · phen) with different phenanthroline contents and the polyphenylene oxides with different phenanthroline contents (Styrene-acrylic acid) carrier iron 5-nitro-phenanthroline complex (SAAC · Fe · Nphen). Elemental analysis and IR results show that SAAC · Fe · phen has the following structure: The catalytic efficiency of the SAAC · Fe · phen- (i-Bu) _3Al binary system is SAAC · Fe-phen- (i- Bu) _3Al ternary system 2 times that of small molecule iron 400 times. In the SAAC · Fe · phen and SAAC · Fe · Nphen systems, the highest catalytic activity is obtained when the molar ratio of phen (or N pnen) / Fe is about 0.7. The catalytic activity increased with the increase of molar ratio of Al / Fe. However, when the mole ratio of Al / Fe was more than 70, the activity tended to be constant. Compared with small molecule iron catalyst, this polymer iron catalyst could increase the polymerization temperature.
