| titleOfInvention | Diphenylmethane diisocyanate composition, isocyanate prepolymer and polyurethane elastomer |
| abstract | The invention relates to a diphenylmethane diisocyanate composition, an isocyanate prepolymer and a polyurethane elastomer, wherein the diphenylmethane diisocyanate composition comprises 2, 4-diphenylmethane diisocyanate, 4-diphenylmethane diisocyanate and 1ppm-15ppm acridine. The prepared diphenylmethane diisocyanate composition has stable activity and small turbidity; the isocyanate prepolymer prepared by the diphenylmethane diisocyanate composition has narrow molecular weight distribution and viscosity temperature, and the polyurethane elastomer prepared by the isocyanate composition has good stability and excellent mechanical property. |
