“…Figure displays XRD patterns of the copolyamides, and all of them are in similar shape. For each pattern, only one broad diffraction peaks at 2θ ≈ 20.0° is observed, indicating that these copolyamides are mainly amorphous, which means the crystallization of PA10T has been successfully disrupted by the introduction of DDA and IPA.…”

Transparent polyamide (TPA) is a type of optically transparent material with high performance, and poly(decamethylene terephthalamide) (PA10T) is an emerging bio‐based opaque polyamide. With the purpose of preparing bio‐based and low‐cost TPA based on PA10T, we chose dodecanedioic acid and isophthalic acid as comonomers, and successfully obtained a series of transparent PA10T/10I/1012. The basic properties of these copolyamides were characterized by intrinsic viscosity measurement, Fourier transform infrared spectrometer, proton nuclear magnetic resonance, X‐ray diffraction, differential scanning calorimetry, thermogravimetric analysis, dynamic mechanical analysis, ultraviolet–visible spectrophotometer, solvent resistance test, water absorption measurement, and tensile measurement. Results show that PA10T/10I/1012 copolymers are amorphous and have high optical transparency. Moreover, these copolymers exhibit high thermal stability, low water absorption, and good solvent resistance, and they also show better mechanical properties compared to some commercial TPAs. © 2018 Wiley Periodicals, Inc.

Itaconic acid, a carbohydrate‐derived aliphatic dicarboxylic acid, is a potential chemical for the synthesis of renewable resource‐based resins and polyesters. Owing to environmental reasons, there is a gradual demand for renewable resources in the chemical industry. Conversely, as a rather underappreciated side effect of this growth, novel chemical building blocks are obtained, which are not commercially derived from petrochemical sources. In this respect, itaconic acid has attracted much attention and its trifunctional structure leads to the synthesis of novel polymeric materials. This review discusses the most relevant information for bio‐based resins and polyesters resulting from itaconic acid and distinctive properties for various commercial applications. © 2017 Society of Chemical Industry

“…However, good macroscopic properties require high exfoliation degree of clay particles, which in turn depend on processing conditions, molecular weight of PA, and backbone polarity. 14,15 Aliphatic-aromatic PAs are important engineering materials having extensive industrial applications due to excellent properties such as toughness, high modulus, and abrasion resistance. [16][17][18] It is customary to characterize the dispersion level of nanoclay layers using various techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy, atomic force microscopy, rheological measurements, and nuclear magnetic resonance.…”

Novel organomodified nanoclay (bentonite) was reinforced in polystyrene, polyamide, and polystyrene/polyamide blend matrix to develop a series of nanocomposites using a solution processing technique. Modification of bentonite nanoclay was performed via an ion-exchange method with L-serine amino acid. Properties of polystyrene/modified bentonite, polyamide/modified bentonite, and polystyrene/polyamide/modified bentonite nanocomposites were studied using Fourier transform infrared spectroscopy, field emission scanning electron microscopy, thermogravimetric analysis, differential scanning calorimetry, X-ray diffraction, and cone calorimetry techniques. A unique honeycomb-like pattern was observed for polystyrene/polyamide blend with 0.5 g modified bentonite content. The morphology analysis revealed a cocontinuous structure in which nanoclay particles were trapped. The polystyrene/polyamide/modified bentonite nanocomposite also showed fine improvement in thermal properties of the system, that is, initial decomposition temperature ¼ 309-321 C and maximum weight loss temperature ¼ 390-400 C. Glass transition temperature (351-385 C) of the series was also higher than the polystyrene/modified bentonite and polyamide/modified bentonite series. Increasing nanoclay content decreased the peak heat release rate of polystyrene/polyamide/modified bentonite 0.5 nanocomposite to 145 kW m À2 , indicating improvement in nonflammability. Moreover, the blend and nanoclay series possess better flame retardancy than the blend and other nanocomposite series developed.
