“…PA10T/1012 is newly synthesized and has not been reported, so the K and α of it cannot be found in the existing literature. However, some researchers used the K and α of PA12T to estimate the molecular weights of other polyamides or copolyamides (such as PA4T, PA6T, PA10T‐ co ‐PA12T, PA12T‐ co ‐PA6T, and PA12T‐PA6 block polymers) . Although the calculation like this is not appropriate in theory and the results might not be the real molecular weight, it still can help to find the approximate range of the molecular weights.…”

“…As presented in Figure (a), each DMA trace presents a single peak, and the peaks of these curves are attributed to the α‐relaxation of amorphous continuous phase . It is well known that the α‐relaxation temperature ( T α ) is associated with glass transition temperature ( T g ), and lots of researchers take T α as T g . In order to qualitatively analyze the thermal performance of these copolyamides, T α is considered as T g in this research.…”

“…The introduction of comonomer with long aliphatic chain can reduce the regularity of molecular chain and the density of amide bonds, which will not only make the melting temperature decrease, but also improve the ductility of PA10T. However, a few reports can be found involving the copolymerization based on PA10T, and none of them aimed at solving the problems mentioned above.…”

Poly(decamethylene terephthalamide) (PA10T), a bio‐based high‐performance semi‐aromatic polyamide, has been commercialized in recent years. However, there still are some weaknesses restricting its application range, such as narrow melt processing window and low ductility. In this study, we chose dodecanedioic acid (a potential bio‐based raw material) as the comonomer to prepare copolyamides [poly(decamethylene terephthalamide/decamethylene dodecanediamide), PA10T/1012] for solving these problems. The basic properties of these copolyamides were characterized by viscosity measurement, Fourier transform infrared spectrometer, proton nuclear magnetic resonance, wide‐angle X‐ray diffraction, differential scanning calorimetry, thermogravimetric analysis, dynamic mechanical analysis, and tensile measurement. Results show that, compared to PA10T, PA10T/1012 exhibits wider melt processing window and more outstanding elongation at break. Meanwhile, PA10T/1012 is still qualified for high temperature resistant material. Furthermore, Tg, Td,5%, Td,10%, and Td,max of PA10T/1012 show a linear dependence on 1012 content, which is helpful to design new bio‐based copolyamides for meeting the needs of various occasions. © 2018 Wiley Periodicals, Inc.

“…The simplest form of PPA is that formed by a single straight-chain aliphatic diamine and a single aromatic acid, TPA or IPA. The series of diamines, from 2-carbon to 13-carbon, with TPA has been studied in parts by various workers: Shashoua and Eareckson, [90] Morgan and Kwolek, [87] Wang and Zhang, [91] Wang et al, [92] Jackson, [84] Prochase Enterprise Co., Ltd., and [93] Novitsky et al [94] Melting and glass transition temperatures of these polymers are shown in Figure 5. The melting data show the odd/even difference that is common to polymers with straight-chain monomers.…”

Polyamides are a subject of enduring interest because of their variety, their complex internal structures, their commercial importance and versatility, and their various chemistries of preparation and of long‐term use. The present review introduces these polymers and then discusses the first of the above aspects, namely the variety of the polyamides. Here, together, the full family is presented, classified conveniently according to the types and combinations of monomers from which they are constructed. magnified image

“…The semi-aromatic transparent nylon (nylon10I/10T) has the advantages over aromatic transparent nylons, such as favorable melt processability, and aliphatic transparent nylons, such as superior thermal and mechanical properties [5,6]. It is worth noting that the commercially available semi-aromatic transparent nylon 6–3-T offers excellent transmittance.…”

Herein, we report a novel transparent engineering plastic nylon 10I/10T based on bio-based poly(decamethylene isophthalamide) (nylon10I). We have demonstrated the one-step melt polycondensation synthesis of transparent nylon and carried out Fourier transform infrared spectroscopy (FT-IR) and proton nuclear magnetic resonance (1H NMR) to confirm the chemical structure. Furthermore, the dynamic mechanical analysis (DMA) and thermogravimetric analysis (TGA) were used to analyze the thermal properties. Glass transition temperature (Tg) and thermal decomposition onset temperature (T1) of nylon 10I/10T (15 wt. % 10T) were 118.9 and 438.0 °C, respectively. The intrinsic viscosity, water absorption, light transmittance, mechanical properties, solvent resistance and the decomposition mechanism of nylon 10I/10T have also been investigated. The results show that the nylon 10I/10T has lower water absorption and enhanced solvent resistance compared to nylon 6–3-T, which indicates that nylon 10I/10T is a promising transparent plastic.
