| titleOfInvention | Polyesterimide and its precursor with low linear thermal expansion coefficient |
| abstract | INDUSTRIAL APPLICABILITY The present invention has a practically useful polyesterimide, precursor thereof, and production thereof having a low dielectric constant, a low linear thermal expansion coefficient, a high glass transition temperature, and sufficient film toughness for flexible printed wiring board applications. A method is provided. Formula (2): In the formula, A and B are each independently a divalent aromatic group, an alicyclic group, or a combination thereof, provided that all the divalent bond positions relative to adjacent atoms are all A polyesterimide comprising a repeating unit represented by the para-position or a relationship corresponding thereto. |
