| 中文摘要 | the novel poly(aryl ether ketone)s containing chloro-side group were synthesized by nucleophilic substitution reactions of 4,4'-biphenol and chlorohydroquinone with either 4,4'-difluorobenzophenone(bp/ch/df) or 1,4-bis(p-fluorobenzoyl)benzene (bp/ch/bf) and their thermotropic liquid crystalline properties were characterized by a variety of experimental techniques. the thermotropic liquid crystalline behavior was observed in the copolymers containing 50 and 70% biphenol. melting transition (tm) and isotropization transition (ti) both appeared in the dsc thermograms. a banded texture was formed after shearing the sample in the liquid crystalline state. the novel poly(aryl ether ketone)s had relatively higher glass transition temperature (tg) in the range of 168 similar to 200 degrees c and lower melting temperature (tm) in the range of 290 similar to 340 degrees c. the thermal stability (td) was in the range of 430 similar to 490 degrees c. |
