  The invention relates to a resin composition which comprises a polymer having a divalent oligofluorene as a repeating unit therein, wherein the divalent oligofluorene contains at least two fluorene units optionally having a substituent, and the 9-positioned carbon atoms of the fluorene units bond to each other via a direct bond or via an alkylene group optionally having a substituent, an arylene group optionally having a substituent, or an aralkylene group optionally having a substituent, and a ratio of a retardation measured at a wavelength of 450 nm (Re450) to a retardation measured at a wavelength of 550 nm (Re550) satisfies the following formula (2): Re450/Re550≦1.0.

  本发明涉及一种树脂组合物，其中包括具有二价寡聚芴作为重复单元的聚合物，其中二价寡聚芴包含至少两个芴单元，可选地具有取代基，并且芴单元的9位碳原子通过直接键或通过可选具有取代基的烷基、芳基或芳基烷基相互结合。在450nm波长（Re450）和550nm波长（Re550）下测得的减速比之比（Re450/Re550）符合以下公式（2）：Re450/Re550≦1.0。

  The present invention relates to copolyethers constitut­ed by copolymers of 7,oxa-bicyclo(2,2,1)-heptane, and its alkyl-derivatives, with one or more single-ring or condens­ed-rings cycloaliphatic ethers, comprising the characteris­tic group: wherein Rʹ is hydrogen and Rʺ is H, a halogen, or an alkyl radical containing a small number of carbon atoms, possibly halogen-substituted. If the ether contains one ring only, it contains from 5 to 12 atoms in the ring, and if it contains a condensed-­rings system, it contains a total number of from 10 to 18 atoms in the rings. Those copolyethers show an anisotropic behaviour in the molten state, and therefore are endowed with liquid-crystal properties.

  本发明涉及由7,氧杂双环(2,2,1)-庚烷及其烷基衍生物与一个或多个单环或缩环脂环族醚的共聚物构成的共聚物，共聚物包含特征基团：其中Rʹ为氢，Rʺ为H、卤素或含有少量碳原子的烷基，可能是卤素取代的烷基。 如果醚只含有一个环，则环中含有5至12个原子，如果醚含有缩环体系，则环中含有10至18个原子。 这些共聚物在熔融状态下表现出各向异性，因此具有液晶特性。
