Abstract

An m-phenylenediamine compound is represented by the following General Formula (I), (II), or (III). R 1 represents a hydrogen atom, an alkyl group, a cycloalkyl group, or an aryl group. R 2 , R 3 , and R 4 each represent an alkyl group. R 5 and R 6 each represent an alkyl group. X represents a chlorine atom or a bromine atom. A method for producing a polymer compound includes obtaining a polymer compound by using the m-phenylenediamine compound represented by General Formula (I) as a raw material.

Claims (12)

1. An m-phenylenediamine compound represented by General Formula (I),

in the formula, R 1 represents a hydrogen atom, an alkyl group, a cycloalkyl group, or an aryl group; and R 2 , R 3 , and R 4 each represent an alkyl group.

2. An m-phenylenediamine compound represented by General Formula (II),

in the formula, R 1 represents a hydrogen atom, an alkyl group, a cycloalkyl group, or an aryl group; R 2 , R 3 , and R 4 each represent an alkyl group; and R 5 and R 6 each represent an alkyl group.

3. The m-phenylenediamine compound according to claim 2 , wherein in General Formula (II), R 5 and R 6 each represent a trifluoromethyl group.

4. An m-phenylenediamine compound represented by General Formula (III),

in the formula, R 2 , R 3 , and R 4 each represent an alkyl group; R 5 and R 6 each represent an alkyl group; and X represents a chlorine atom or a bromine atom.

5. The m-phenylenediamine compound according to claim 4 , wherein in General Formula (III), R 5 and R 6 each represent a trifluoromethyl group.

6. The m-phenylenediamine compound according to claim 4 , wherein in General Formula (III), X represents a chlorine atom.

7. The m-phenylenediamine compound according to claim 5 , wherein in General Formula (III), X represents a chlorine atom.

8. A method for producing a polymer compound, the method comprising obtaining a polymer compound by using the m-phenylenediamine compound according to claim 1 as a raw material.

9. The method for producing a polymer compound according to claim 8 , wherein the polymer compound is a compound selected from a polyimide compound, a polyurethane compound, a polyurea compound, and a polyamide compound.
