Abstract

The present invention relates to a polyisocyanate composition comprising, on the basis of the total mass of the polyisocyanate composition, 97 mass % or more of a polyisocyanate; and 2.0 mass ppm to 1.0×10 4 mass ppm of a compound represented by the formula (1):

wherein R 1 is an aliphatic group having 6 to 70 carbon atoms, R 2 is an aromatic ring, a is an integer of 1 to 5, b is an integer of 0 to 4, and the sum of a and b is 2 to 5.

First claim

The invention claimed is:

1. A polyisocyanate composition comprising, on the basis of a total mass of the polyisocyanate composition:
97 mass % or more of a polyisocyanate; and
2.0 mass ppm to 1.0×10 4 mass ppm of a compound represented by the formula (1):

wherein R 1 is an aliphatic group having 6 to 70 carbon atoms, R 2 is an aromatic ring, a is an integer of 1 to 5, b is

an integer of 0 to 4, and the sum of a and b is 2 to 5.

2. The composition according to claim 1 , further comprising a compound having at least one unsaturated bond,
wherein the unsaturated bond is a carbon-carbon double bond or a carbon-oxygen double bond,
the carbon-carbon double bond is not a carbon-carbon double bond that constitutes an aromatic ring, and
said compound having at least one unsaturated bond and said compound represented by formula (1) are different.

3. The composition according to claim 2 , wherein the compound having at least one unsaturated bond comprises a carbonic acid derivative.

4. The composition according to claim 3 , wherein the carbonic acid derivative is at least one carbonic acid ester selected from the group consisting of dimethyl carbonate, diethyl carbonate, dibutyl carbonate, dipentyl carbonate, and dihexyl carbonate; or an N-unsubstituted carbamic acid ester.

5. The composition according to claim 1 , further comprising at least one compound selected from the group consisting of a hydrocarbon compound, an ether compound, a sulfide compound, a halogenated hydrocarbon compound, a Si-containing hydrocarbon compound, a Si-containing ether compound, and a Si-containing sulfide compound.

6. The composition according to claim 1 , wherein the compound represented by the formula (1) is a compound represented by the formula (1-3) or (1-4):

7. The composition according to claim 6 , wherein the R 1 is a hexamethylene group.

8. The composition according to claim 1 , wherein the R 2 is a group represented by the formula (26-1):

wherein the ring A is a monocyclic or polycyclic aromatic hydrocarbon ring which optionally has a substituent group, and f is an integer of 1 to 3.

9. A manufacturing method of an isocyanate polymer comprising polymerizing the polyisocyanate composition according to claim 1 , wherein
the polyisocyanate comprised in the composition is a diisocyanate, and
the isocyanate polymer has a unit represented by formula (2) and at least one unit selected from the group consisting of units represented by formulas (3), (4), (5), (6), (7), (8), and (9), respectively,

wherein each R 3 independently is a divalent hydrocarbon group, and each R 4 is independently a monovalent organic group.
