The present invention relates to polyisocyanate compositions and isocyanate polymer compositions. A polyisocyanate composition comprising, based on the total mass of the polyisocyanate composition: 97% by weight or more of a polyisocyanate; and 2.0 ppm by mass or more and 1.0X 10 4 A compound having at least 1 unsaturated bond different from the polyisocyanate in mass ppm or less; or 5.0 ppm by mass or more and 2.0X 10 4 The inert compound is at most one selected from the group consisting of hydrocarbon compounds, ether compounds, thioether compounds, halogenated hydrocarbon compounds, silicon-containing ether compounds and silicon-containing thioether compounds. |
