XYLYLENEDIAMINE COMPOSITION AND METHOD FOR PRODUCING POLYAMIDE RESIN |
| 摘要 |
Provided are [1] a xylylenediamine composition containing xylylenediamine and 1,2-ditolylethane wherein the content of 1,2-ditolylethane is 0.001 to 0.02 parts by mass based on 100 parts by mass of the xylylenediamine; and [2] a method for producing a polyamide resin including the steps of introducing a diamine containing xylylenediamine, a dicarboxylic acid, and 1,2-ditolylethane into a reaction system and performing polycondensation reaction, wherein the amount of the 1,2-ditolylethane to be introduced is 0.001 to 0.02 parts by mass based on 100 parts by mass of the xylylenediamine. |
