  The diamine composition according to an embodiment of the present invention comprises a benzylmonoamine having a methyl group in an amount of 10 ppm to 2,000 ppm in the composition. When it is used for the preparation of a diisocyanate composition and an optical material, it is possible to improve the optical characteristics by preventing the occurrence of yellowing, striae, and cloudiness in the optical material and enhancing the mechanical properties such as impact resistance at the same time. In addition, in the process for preparing a diisocyanate composition according to another embodiment, the b* value according to the CIE color coordinate of a diamine composition is adjusted to a specific range, whereby it is possible to enhance not only the yield and purity of the diisocyanate composition but also the optical characteristics of the final optical lens. Thus, the process for preparing a diisocyanate composition can be applied to the preparation of a plastic optical lens of high quality.

  根据本发明实施例的二胺组合物包括一种苄基单胺，其中该苄基单胺中含有10 ppm至2,000 ppm的甲基基团。当用于制备二异氰酸酯组合物和光学材料时，可以通过防止光学材料中的发黄、条纹和浑浊的发生，同时提高冲击抗性等机械性能，改善光学特性。此外，在根据另一实施例制备二异氰酸酯组合物的过程中，将二胺组合物的CIE色坐标中的b*值调整到特定范围，不仅可以提高二异氰酸酯组合物的产率和纯度，还可以提高最终光学透镜的光学特性。因此，制备二异氰酸酯组合物的过程可应用于高质量的塑料光学透镜的制备。

  In the production method of the present invention, the polyamide is produced by the polycondensation of a diamine component and a dicarboxylic acid component comprising a straight-chain &agr;,&ohgr;-aliphatic dicarboxylic acid and an aromatic dicarboxylic acid. The dicarboxylic acid component is first made into a suspension phase of the solid aromatic dicarboxylic acid in a molten straight-chain &agr;,&ohgr;-aliphatic dicarboxylic acid. A part of the diamine component is added while the reaction system is in the suspension phase. Then, the reaction system is made into a homogeneous molten phase, to which the rest of the diamine component is added. Finally, the reaction system is kept at temperatures within a specific range to complete the polycondensation.
