Abstract

To provide a polyamide compound having better properties than conventional polyamide compounds.
A polyamide compound comprising a dicarboxylic acid unit represented by the following general formula (1) and a diamine unit represented by the following general formula (2). The polyamide compound of the present invention is characterized by having high energy absorption and high water-absorption resistance rate, and being amorphous (transparent).

First claim

The invention claimed is:

1. A polyamide compound comprising:
a dicarboxylic acid unit represented by the following general formula (1) and a diamine unit represented by the following general formula (2):

 (wherein n represents 11, and m represents 11; R 1 represents n-C 9 H 19 ; and R 2 represents n-C 9 H 19 );

 (wherein A represents a divalent organic group selected from the following group)

2. The polyamide compound according to claim 1 , further comprising:
a diamine unit represented by the following general formula (3):

 (wherein B represents a divalent organic group selected from the following group, with the proviso that A and B are different)

3. The polyamide compound according to claim 1 , wherein
A is the following divalent organic group

4. The polyamide compound according to claim 2 , wherein
A is the following divalent organic group

5. A method for producing the polyamide compound as defined in claim 1 , comprising reacting a dicarboxylic acid compound having a structure represented by the following general formula (4) with a diamine compound:

(wherein n represents 11, and m represents an integer of 11; R 1 represents n-C 9 H 19 , and R 2 represents n-C 9 H 19 ).

6. A method for producing the polyamide compound as defined in claim 2 , comprising reacting a dicarboxylic acid compound having a structure represented by the following general formula (4) with a diamine compound:

(wherein n represents 11, and m represents an integer of 11; R 1 represents n-C 9 H 19 , and R 2 represents n-C 9 H 19 ).

7. A method for producing the polyamide compound as defined in claim 3 , comprising reacting a dicarboxylic acid compound having a structure represented by the following general formula (4) with a diamine compound:

(wherein n represents 11, and m represents an integer of 11; R 1 represents n-C 9 H 19 , and R 2 represents n-C 9 H 19 ).
