| Abstract: | In this paper,the polyketoacid and polyquinone having ladder structure were synthesized from pyromellific dianhydride and diphenyl ether by solution polycondensation in the presence of AlCl 3 as catalyst and 1,2-dichloroethane/pyridine as mixed solvent.We have studied the influence of solvent on the polymerization and thermal cyclization in diffrent temperatures.The polymers were characterized by IR,TG.The results show that the polyketoacid and polyquinone exhibit excellent solvent resistance and thermostability properties. |
