A　specific　polyamide-amide　block　copolymer　with　monomers　of　triethyleneglycol　his　(4-carboxypheny)　ether　(PEG3),　4,4＇-diamino-3,3＇-dimethylbiphenyl　and　epsilon-caprolactam　was　synthesized　via　condensation　copolymerization.　FT-IR,　H-1-NMR,　POM,　DSC　and　WAXD　analyses　of　samples　elicit　that　this　new　type　of　block　copolymer　can　demonstrate　liquid　crystalline　characteristics.　By　contrast　to　thermotropic　homopolyamide　liquid　crystalline　(TLCP),　the　thermal　dynamic　properties　of　the　thermotropic　liquid　crystalline　copolyamide　containing　N6　(TLCP-N6)　were　modified.　This　block　copolymer　can　show　nematic　phase　in　a　wide　temperature　range,　and　is　able　to　form　morphologic　textures　of　solidification-induced　band　and　shear　stripes　under　certain　conditions.
