NOVEL SILICON-CONTAINING ALICYCLIC POLYIMIDE RESIN, POLYAMIC ACID RESIN, AND MANUFACTURING METHOD FOR SAME |
摘要 |
A polyimide resin including repeating units represented by formula (1): wherein R is a diamine residue or a diisocyanate residue; m is an integer of 2 to 30; any of silicon atoms bonded to norbornane rings is in exo configuration with respect to the norbornane rings; and any of imide rings bonded to the norbornane rings is in exo configuration with respect to the norbornane rings, and a polyamic acid resin including repeating units represented by formula (2): wherein R is a diamine residue; m is an integer of 2 to 30; any of silicon atoms bonded to norbornane rings is in exo configuration with respect to the norbornane rings; and any of amide groups and carboxyl groups bonded to the norbornane rings is in exo configuration with respect to the norbornane rings. The polyimide resin is soluble in general-purpose solvents, has a good transparency and a high molecular weight, and is excellent in mechanical properties, such as tensile strength and elongation.
