ALICYCLIC POLYAMIDE, ITS PRODUCTION METHOD AND USAGE
PROBLEM TO BE SOLVED: To develop a new alicyclic polyimide and a production method for the same. SOLUTION: This alicyclic polyimide has structure expressed by formula (I), wherein R is a cyclic aliphatic group, Cl and Cn are each substituted 2-7C alkylene or alkenylene group, Cm is bonded 0-2C alkyl...

Zusammenfassung: | PROBLEM TO BE SOLVED: To develop a new alicyclic polyimide and a production method for the same. SOLUTION: This alicyclic polyimide has structure expressed by formula (I), wherein R is a cyclic aliphatic group, Cl and Cn are each substituted 2-7C alkylene or alkenylene group, Cm is bonded 0-2C alkylene or alkenylene group (for example, a single bond, double bond, methylene group, ethylene group or ethenylene group), p is an integer of 1-8 and x is the integer of 1 or above. This alicyclic polyimide is produced by a copolymerization process of a polycyclic diacid anhydride and a cyclic aliphatic diamine and by a transformation process to an alicyclic polyimide having the structure expressed by formula (I) by a cyclization reaction. |
