摘要：

Using bio-based pentane diamine, hexamethylene diamine and terephthalic acid as raw material, heat-resistant polyamide poly (pentamethylene terephthalamide-co-hexamethylene diamine) (PA5T/6T) copolymers were synthesized. The use of low-temperature drainage technology effectively inhibited the side reaction of pentanediamine deamination and cyclization, and high viscosity PA5T/6T was obtained. Compared with traditional high temperature resistant nylon PA6T/66 (hexamethylene terephthalamide-co-hexamethylene adipamide), bio-based high temperature resistant nylon PA5T/6T has 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. © 2021, Editorial Board of Polymer Materials Science & Engineering.
