“…English and coworkers14–16 reported an extensive NMR study of selectively deuterated nylon‐66 samples in which it was shown that the mobility of the crystalline regions were distinct between the methylene units of the diacid and diamine. The six diamine methylene units were found to have more restricted mobility than the four diacid methylene units.…”

High-aliphatic-content linear nylons were produced with an 18-carbon diacid with diamines containing both odd and even methylene segments. The resulting polymers were characterized with viscosimetric, thermal, and spectroscopic techniques. Solid-state 15 N NMR was used to determine the nylon crystalline form present. © 2005 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 43: 936 -945, 2005

“…The behavior of secondary amide groups is well known (54), but the length of the CH sequence introduces an additional dimension to the properties of nylons, because the CH2 sequence may have a different degree of crystalhnity in the different stereoisomer structures (55). FT Raman spectroscopy was used (56) to confirm previous spectroscopic findings on nylon fibers and illustrated that indeed FT Raman spectroscopy can produce fluorescence-free Raman spectra. Typical spectra of nylon-6,6 and nylon-6,12 are shown in Figure 16.…”

This chapter covers the fundamental principles and current applications of Fourier transform (FT) infrared and Fourier transformRaman spectroscopies as utilized in the analysis of polymeric materials. The primary emphasis of the first part is on the principles and advantages of these interferometric methods, whereas the remaining sections illustrate numerous applications focusing on the structure--property considerations in polymers. Particular attention is given to the most recent developments in FT analysis and includes examples of structural and conformational analysis of polymers, biological studies, and the applications of FT infrared and Raman microscopy to remote measurements. The differences and the complementary nature of infrared and Raman spectroscopies are also presented. EJXPERIMENTAL SCIENCES HAVE BEEN PROFOUNDLY INFLUENCED by the development of novel instrumentation. Virtually all scientific instrumentation is now under computer control, and sophisticated, faster data collection allows scientists to channel their resources more effectively toward particular goals. The sophistication of many current physical approaches mandates the use of highly sensitive, fast instruments and reasonably powerful data acquisi tion computers to attain insights about fundamental aspects of processes under investigation. Examples of such sophisticated interplay are infrared and

“…Semiaromatic polyamides combine the excellent thermal and mechanical properties of wholly aromatic polyamides with the favorable toughness and processability of aliphatic polyamides. They have received widespread attention and been developed worldwide in recent years, especially for applications in the electric and automobile industries 1–6 . As a novel semiaromatic polyamide, PA10T was synthesized by polycondensation of 1,10‐decanediamine (DMD) and terephthalic acid (TPA), and found to have excellent mechanical properties, outstanding heat and solvent resistance, dimensional stability, and low water absorption 7,8 .…”

A novel silicone monomer modified poly(decamethylene terephthalamide) PA10T is synthesized from 1,10‐decanediamine (DMD), terephthalic acid, and 1,3‐bis(3‐aminopropyl)tetramethyldisiloxane (DS2). The chemical structure of the product is characterized using Fourier transform infrared spectrometry and nuclear magnetic resonance. The crystallization behavior, thermal properties, and mechanical properties of PA10T are also analyzed. Copolymerization of PA10T with DS2 results in reduced crystallinity and thermal properties, but to a lesser extent than when PA10T is modified with aliphatic polyamide. With increased DS2 content, the tensile strength of PA10T decreases gradually, while the elongation at break and impact strength increase significantly, indicating that the toughness of PA10T has been improved.
