| 摘要 |
<p>The present invention relates to a method for manufacturing aα,ω-diamine, which is a raw material of a polyimide based thermoplastic elastomer (TPE) by usingα,ω-dicarboxylic acid wherein theα,ω-dicarboxylic acid is synthesized from natural oil. The method in the present invention is allowed to manufacture aα,ω-diamine used as a polyimide monomer and manufacture aα,ω-diamine with various carbon numbers. In addition, the method of the present invention is considered as an eco-friendly manner becauseα,ω-dicarboxylic acid used as an initiating material can be easily manufactured from natural oil.</p> |
