摘要 PCT No. PCT/FI95/00381 Sec. 371 Date Dec. 23, 1996 Sec. 102(e) Date Dec. 23, 1996 PCT Filed Jun. 30, 1995 PCT Pub. No. WO96/01284 PCT Pub. Date Jan. 18, 1996The present invention relates to liquid crystalline copoly(ester-imides) and a process for the preparation thereof. In particular, the invention relates to liquid crystalline copoly(esteri-imides) comprising structural units derived from N-(3'-hydroxyphenyl)-trimellitic acid imide or N-(4'-carboxyphenyl)trimellitic acid imides optionally in combination with aromatic dicarboxylic acids, dioles or hydroxy acids. The invention also concerns the use of these copolymers in polymer blends, in moulded articles, in fibres, filaments and sheets.
