Vertical alignment polyimide and vertical alignment film compositions for LCD |
| 摘要 |
A vertical alignment polyimide for LCD has the following structure: wherein R<SUB>1 </SUB>and R<SUB>2 </SUB>are same or different tetravalent aromatic residues or alkyl residues; n is an integer, and 24>=n>=6; a:b=1:9 to 9:1, preferably from 4:1 to 1:1; and a+b=p+q. The polyimide has an inherent viscosity of 0.04-5 dl/g.
