Description

  The present invention relates to a polymer compound having excellent heat resistance, mechanical properties, chemical stability, and transparency and having excellent processability useful for applications such as structural materials, electronic materials, and optical materials.

  Polyarylene such as polyphenylene having an aromatic ring chain structure is a polymer excellent in properties such as thermal stability, mechanical properties (high elastic modulus), and chemical stability (chemical resistance). However, a polymer having an aromatic ring chain structure is inferior in solubility in an organic solvent and has a limit in processability. As a method for improving the solubility, there is an attempt to introduce a side chain as a soluble group. However, when side chains are introduced, the heat resistance tends to decrease, and the production of raw materials tends to become complicated.

  Examples of conventional polyphenylene include the polymers described in Patent Documents 1 to 5. These polymers basically have a structure mainly composed of a rigid structure made of parapolyphenylene. However, if the polymer is processed into a sheet shape and then subjected to a stretching process, the polymer breaks and cannot be stretched.

  At present, there is a demand for a polymer compound excellent in processability such as stretching treatment while maintaining heat resistance, mechanical properties, chemical stability, and transparency inherent in polyphenylene.
