| Abstract: | Poly(m phenylene isophthalamide) containing chlorine substituent (PMIAC) was synthesized by low temperature solution polycondensation of 2,5-dichloro-1,4-benzenedicarbonyl chloride (DDC),isophthaloyl chloride (IPC) and m-phenylenediamine (MPD) in DMAc.The effects of the molar concentration of monomer,reaction temperature,tertiary amines and molar ratio of DDC to IPC on the polycondensation reaction were investigated.It has been found that the molecular weight of the copolymer (PMIAC) increases obviously when α-methylpyridine is used as additive in the polymeric reaction,and the molecular weigh t of PMIAC decreases with increase in molar ratio of DDC to IPC. The copolymer (PMIAC) was characterized by IR and TG. |
