| Abstract: | A series of fluorinated polyamides was prepared by using low temperature solution polycondensation,with DBTF as the third monomer,m-phenylenediamine(MPD)and m-phthaloyl chloride(IPC)in dimethylacetylamide(DMAc) as the raw materials.The factors which could affet the polymerization reactions were researched.The conditions of polymerization were as follows:the initial polycondensation temperature was-5,℃,IPC excess was 2‰,monomer concentration was 1,mol/L and the reaction time was 80,min.The viscosity of the obtained fluorinated polyamides was 0.81-1.43,dL/g.The structure and mechanical properties of the fluorinated polyamide were characterized by various means. |
