研究天然氨基酸作用下ε-己内酯在微波场中的开环聚合反应。在微波聚合中,微波功率、反应时间、氨基酸的浓度等对聚合反应有显著的影响,在微波功率510 W、ε-己内酯与L-苯丙氨酸摩尔比等于60、反应时间4 h的条件下,可得到重均分子量(w)为13.3 kg/mol的聚(ε-己内酯)。红外(FTIR)和核磁共振(1H-NMR)分析证实氨基酸连接到聚合物链上。
To study the ring-opening polymerization of ε-caprolactone in a microwave field by natural amino acids. In the microwave polymerization, microwave power, reaction time, concentration of amino acids, etc. have a significant impact on the polymerization reaction, the microwave power of 510 W, ε-caprolactone and L-phenylalanine molar ratio equal to 60, the reaction time of 4 h , Poly (ε-caprolactone) with a weight average molecular weight (ww) of 13.3 kg / mol was obtained. Infrared (FTIR) and nuclear magnetic resonance (1H-NMR) analyzes confirmed the attachment of amino acids to the polymer chain.
