Enzyme catalyzed synthesis of renewable polyamides was investigated using lipase B. A fatty acid-derived AB-type functional monomer, having one amine and one methyl ester functionality, was homopolymerized at 80 and 140 °C. Additionally, the organobase 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) was used as a catalyst. The results from the two catalysts were comparable. However, the amount of lipase added was 1.2 × 10 times lower, showing that the lipase was a more efficient catalyst for this system as compared to TBD. Moreover, the AB-type monomer was copolymerized with 1,12-diaminododecane to synthesize oligoamides of two different lengths.
使用脂肪酶B研究了酶催化合成可再生聚酰胺的过程。一种具有一个胺基和一个甲酯官能团的脂肪酸衍生的AB型功能单体在80℃和140℃下进行了均聚。此外，有机碱1,5,7-三氮杂双环[4.4.0]癸-5-烯（TBD）被用作催化剂。两种催化剂的结果具有可比性。然而，脂肪酶的添加量低1.2×10倍，这表明与TBD相比，脂肪酶是该体系中更有效的催化剂。此外，AB型单体与1,12-二氨基十二烷共聚以合成两种不同长度的低聚酰胺。
