摘要
以生物基戊二胺、己二胺和对苯二甲酸为原料,通过预聚+固相增黏工艺合成耐高温尼龙聚(对苯二甲酰戊二胺-共-己二胺)(PA5T/6T)共聚物。使用低温排水工艺有效抑制了戊二胺脱氨环化副反应,得到高黏度PA5T/6T。相对于传统耐高温尼龙(对苯二甲酰-共-己二酰-己二胺)PA6T/66,生物基耐高温尼龙PA5T/6T具有玻璃化转变温度高(155℃vs.103℃)、热滞留保持率高(77%vs.19%)、力学性能佳和熔接痕强度高等突出优势。
Using bio-based pentane diamine,hexamethylene diamine and terephthalic acid as raw material,heat-resistant polyamide poly(pentamethylene terephthalamide-co-hexamethylene diamine)(PA5T/6 T)copolymers were synthesized.The use of low-temperature drainage technology effectively inhibited the side reaction of pentanediamine deamination and cyclization,and high viscosity PA5T/6 Twas obtained.Compared with traditional high temperature resistant nylon PA6T/66(hexamethylene terephthalamide-co-hexamethylene adipamide),bio-based high temperature resistant nylon PA5T/6 Thas outstanding advantages of a high glass transition temperature(155℃vs.103℃),high heat retention rate(77%vs.19%),good mechanical properties,high strength of weld mark,etc.
