Abstract
Heat-resistant semi-aromatic poly (decamethylene terephthalamide) acid (PA10T) and a series of poly (decamethylene terephthalamide/decamethylene furanamide) (PA10T/10F) with a high content of bio-based carbon were synthesized by a cost-effective high-pressure solution polycondensation method. The chemical structures of the obtained samples were evaluated by Fourier infrared spectroscopy (FT-IR). Moreover, the effect of the addition of copolymer 2,5-furandicarboxylic acid (FDCA) and the copolymerization ratios of FDCA for PA10T on thermal performances, crystallization behaviors, and mechanical properties of PA10T and PA10T/10F were studied in detail. In addition, the results of DSC indicate that the melting points of PA10T/10F copolyamides can be adjusted appropriately by varying the feed ratios of FDCA, suggesting the improvement of processabilities. Besides, with increasing the copolymerization ratios of FDCA, the sizes of spherulites decreased gradually analyzed by POM. Furthermore, the results of XRD showed that the PA10T homopolymer and PA10T/10F copolyamides possess similar shapes around 2θ = 21°. In addition, compared with pure PA10T, the tensile strength, breaking elongation, bending strength, bending modulus, and izod impact strength all increased obviously when the feed ratio of FDCA and terephthalic acid (PTA) was 5:95. Therefore, the crystallization behaviors, processing performances, and mechanical characteristics of PA10T can be improved significantly by introducing FDCA, to improve the bio-based carbon content of PA10T and meet the increasing demand for environmentally friendly materials all over the world.
期刊介绍：
"Polymer Bulletin" is a comprehensive academic journal on polymer science founded in 1988. It was founded under the initiative of the late Mr. Wang Baoren, a famous Chinese chemist and educator. This journal is co-sponsored by the Chinese Chemical Society, the Institute of Chemistry, and the Chinese Academy of Sciences and is supervised by the China Association for Science and Technology. It is a core journal and is publicly distributed at home and abroad.
"Polymer Bulletin" is a monthly magazine with multiple columns, including a project application guide, outlook, review, research papers, highlight reviews, polymer education and teaching, information sharing, interviews, polymer science popularization, etc. The journal is included in the CSCD Chinese Science Citation Database. It serves as the source journal for Chinese scientific and technological paper statistics and the source journal of Peking University's "Overview of Chinese Core Journals."
