| titleOfInvention | Diaminobenzene derivative, polyimide obtained therefrom, and liquid-crystal alignment film |
| abstract | An alkyldiamine having excellent polymerization reactivity, a polyimide containing it as a component, and a liquid crystal alignment film excellent in liquid crystal alignment uniformity are provided. That is, the present invention relates to a diaminobenzene derivative represented by the following general formula (1), and further reacts a diamine containing 1 mol% or more of the compound of the general formula (1) with tetracarboxylic dianhydride and a derivative thereof to reduce the viscosity A polyimide having a repeating unit represented by the formula (2), which is a polyimide precursor having 0.05 to 5.0 dl / g (concentration of 0.5 g / dl in N-methylpyrrolidone at a temperature of 30 ° C.), and the ring is closed. will be. The present invention also relates to a liquid crystal alignment film comprising 1 mol% or more of the repeating unit:n n n n n n n n (In Formula 1, X and P are respectively independently a single bond or a divalent organic group chosen from -O-, -COO-, -OCO-, -CONH-, -NHCO-, and Q is a 1-22 series. A linear alkyl group or a linear fluorine-containing alkyl group, a represents an integer of 1 to 4, the number of substituents, R is a substituent selected from fluorine, a methyl group and a trifluoromethyl group, and b is an integer of 1 to 4 substituents Represents a tetravalent organic group constituting tetracarboxylic acid, and B represents a divalent organic group constituting diamine. |
