Abstract
本研究中所採行Nylon 6t聚合是以雙醯氯及雙胺之界面聚合的方式，利用醯氯的活性大於酸類的特點並於兩相的溶劑系統之下反應藉以得到Nylon6t的聚合產物。並藉由界面聚合反應，研究醯氯及胺類合成Nylon的反應性。
本研究將以幾種不同的比例，籍改變其反應條件，試著得到最佳的比例配方及反應條件：
1．將不同的胺類依照不同的濃度進行界面聚合反應，觀察聚合產物的分子量，耐熱性之變化。
2．利用改變不同的反應溶劑所合成的Nylon並觀察界面聚合反應產物的分子量、耐熱性之變化情形。
3．改變不同的反應溫度合成Nylon並觀察界面聚合反應後的產物之分子量、耐熱性之變化情形。
將界面聚合反應後之聚合物作分子量、DSC、TGA、等性質測試，並評估本計畫可否用於量產。
This study on nylon6T is from diacid chloride and diamine interfacial polymerization. Producing nylon 6t is even easier if you use a diamine and a diacid chloride instead of a diacid. This is because acid chlorides are much higher reactive than the acids with amine . In order to get the optimized reaction condition of the nylon materials, we will carry out the studies of interfacial polymerization between diacid chloride and diamine.
It seems a good method to tune different kinds of reaction conditions to achieve our final goals:
1. Produce nylon by using diacid chlorides and diamines for Nylon6t polymerization. Measure the properties of the polymerized products.
2. Synthesis nylons with different kinds of biphase solvent systems. Test the mechanical properties and heat-resistance changes.
3．Produce nylon by changing the temperature of the interfacial polymerized reaction.
Test the mechanical properties and heat-resistance changes.Compare the results of DSC, TGA, And then estimate this project for the practical application in the industry.
