Abstract

A triazine-ring-containing polymer characterized by including a repeating unit structure represented by formula (1).

[In the formula, R and R′ each independently represent a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, or an aralkyl group, and
Ar represents at least one selected from the group shown by formulas (2) and (3).

[in the formulas, W 1 and W 2 each independently represent CR 1 R 2 (R 1 and R 2 each independently represent a hydrogen atom or a C1-10 alkyl group optionally substituted by a halogen atom (where these together may form a ring)), C═O, S, SO, or SO 2 .]]

First claim

The invention claimed is:

1. A triazine-ring-containing polymer comprising a repeating unit structure represented by the following formula (1):

wherein R and R′ each independently represent a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, or an aralkyl group, and
Ar represents at least one selected from the group represented by formulas (2) and (3),

wherein W 1 and W 2 are each independently CR 1 R 2 (R 1 and R 2 each independently represent a hydrogen atom or an alkyl group having 1 to 10 carbon atoms, which may be substituted with a halogen atom (provided that these groups may together form a ring)), CO═O, S, SO, or SO 2 .

2. The triazine-ring-containing polymer according to claim 1 , wherein the W 1 and W 2 each independently represent CR 1 R 2 (R 1 and R 2 each independently represent a hydrogen atom or an alkyl group having 1 to 10 carbon atoms, which may be substituted with a halogen atom), or O.

3. The triazine-ring-containing polymer according to claim 1 , wherein the Ar is represented by the formula (4).

4. The triazine-ring-containing polymer according to claim 3 , wherein the Ar is represented by the formula (5).

5. The triazine-ring-containing polymer according to claim 1 , wherein the Ar is represented by the formula (6) or (7).

6. The triazine-ring-containing polymer according to claim 5 , wherein the Ar is represented by the formula (8) or (9).

7. A triazine-based polymer-containing composition comprising the triazine-ring-containing polymer according to claim 1 and an organic solvent.

8. The triazine-based polymer-containing composition according to claim 7 , further comprising a crosslinking agent.

9. The triazine-based polymer-containing composition according to claim 8 , wherein the crosslinking agent is a polyfunctional (meth)acrylic compound.

10. A film obtained from the triazine-based polymer-containing composition according to claim 7 .

11. A pattern prepared from the triazine-based polymer-containing composition according to claim 8 .

12. An electronic device comprising: a substrate; and the film according to claim 10 , formed on the substrate.

13. An optical member comprising: a substrate; and the film according to claim 10 , formed on the substrate.

14. An electronic device comprising: a substrate; and the pattern according to claim 11 , formed on the substrate.
