  1. 发明领域 重试    错误原因
本发明涉及一种制造处理过的聚合物的方法，更具体地说，涉及一种用于液晶取向剂的处理过的聚合物的制造方法。本发明还涉及一种含有经处理聚合物的液晶取向剂、由液晶取向剂形成的液晶取向膜，以及包括液晶取向膜在内的液晶显示元件。 重试    错误原因
  1. 相关技术说明 重试    错误原因
液晶显示元件广泛用于计算机的屏幕、照相机的取景器、投影显示器、电视屏幕等。 重试    错误原因
向列液晶显示元件主要用于一般的液晶显示元件，实际使用的向列液晶显示元件的具体实例包括：（1）TN（扭曲向列）液晶显示元件，其中一侧基板的液晶取向相对于另一侧基板的液晶取向扭曲成90度角;（2）一种STN（Super Twisted Nematic）液晶显示元件，其中一侧基板的液晶取向相对于另一侧基板的液晶取向扭曲成大于180度的角度;（3）使用薄膜晶体管的TFT（薄膜晶体管）液晶显示元件。 重试    错误原因
本领域不断尝试改进液晶取向膜，以增强液晶显示元件的显示性能，例如减少图像粘连问题。 重试    错误原因
液晶取向膜由液晶取向剂制成。传统上，液晶取向剂是通过将聚酰胺酸或可溶性聚酰亚胺溶解在有机溶剂中，然后在基材上施加和固化以形成液晶取向膜而配制的。 重试    错误原因
图像粘贴问题是由剩余直流 （DC） 电压引起的。具体来说，当残余直流电压较大时，即使电场关闭后，一旦打开，它也会保持不变。在这种情况下，要擦除的图像将保持图像粘贴状态。因此，希望残余 电压无穷小地趋近于零。这种图像粘连现象是液晶显示元件中最重要的问题之一。 重试    错误原因

A co-precipitating solvent for the untreated polyamic acid (A-1) is prepared, which includes a major amount of a poor solvent and a minor amount of a good solvent. 重试    错误原因
The good solvent is a solvent having a good solubility for the polymer (A) (i.e., polyamic acid (A-1), polyimide (A-2), polyimide series block copolymer (A-3), or combinations thereof), and examples thereof are those for the aforesaid organic solvent. 重试    错误原因
The poor solvent is a solvent having a relatively poor solubility for the polymer (A), and examples of the poor 15 solvent suitable for the present invention are a ketone (such as, acetone), an ether (such as, tetrahydrofuran), and a combination thereof. 重试    错误原因
Preferably, the poor solvent is in an amount of 800 to 900 parts by weight based on 1,000 parts by weight of the coprecipitating solvent. 重试    错误原因

Heating temperature for the imidization processing is generally from 40 to ., and preferably from 80 to . 重试    错误原因
If the reaction temperature of the imidization processing is lower than ., then the dehydration ring-closing reaction cannot be fully implemented. If the reaction temperature exceeds ., then the weight average molecular weight of 45 the obtained polyimide (A-2) is reduced. 重试    错误原因
Examples of the dehydrating agent suitable for the imidization processing include an acid anhydride compound, such as acetic anhydride, propionic anhydride, trifluoroacetic anhydride, and the like.
