“…The importance of incorporating polymer chemistry into the undergraduate curriculum has been emphasized by the American Chemical Society’s Committee on Professional Training . Many polymer-based laboratory experiments have been developed as epitomized most recently in the Journal of Chemical Education Special Issue: Polymer Concepts Across the Curriculum . − In addition to the special issue, there are several specific examples focused on the class of polyamides frequently referred to as nylon. − …”

Synthesis, Modification, and Application of Sulfonated Poly(styrene-co-maleic anhydride) as a Stain Blocker for Polyamides: Polymer Chemistry for the Undergraduate Organic Laboratory

A laboratory exercise for the synthesis of a sulfonated styrene-co-maleic anhydride polymer and its application as a stain blocker on nylon-6,10, is described. The effectiveness of the sulfonated polymer to prevent the conjugate base of an acid dye from staining the polyamide is demonstrated. This experiment is designed for second-semester, second-year undergraduate organic chemistry students. Specifically, this laboratory experiment focuses on providing experience with radical chain and step-growth polymerizations, interfacial reactions, electrophilic aromatic substitution (sulfonation), and the importance of intermolecular forces.

“…Functional groups and their ability to interact in the crystal lattice are also of major help in the crystallization process. Since the seminal experimental work by Carothers and his team at the DuPont company in the early 1930s, it is well-known that increasing the tendency for polymer chains to interact with each other enhances dramatically the system’s ability to crystallize and greatly raise the obtained melting points. − For example, aliphatic polyamides (nylons) have a much higher inclination to crystallize than their polyester analogues, the melting points in this case increasing with the density of the secondary carboxamide −(CO)–NH– groups located in the backbone at regular intervals.…”

Synthesis, Characterization, and Solid-State Properties of (CH₂–CH₂–C(COOH)₂)_n: A Highly Symmetrical, Semicrystalline Carbon-Chain Poly(carboxylic acid)

et al. 2020

The synthesis and structural characterization of poly(trimethylene-1,1dicarboxylic acid), (CH 2 -CH 2 -C(COOH) 2 ) n , a carbon-chain polymer bearing two carboxylic acids on every third carbon alongside the backbone is described for the first time. Solid-state properties are investigated by a variety of techniques (WAXS, FT-IR, CP-MAS, TGA), in particular with respect to the semi-crystalline character of the polymer and its affinity toward water. The observed experimental features are rationalized on the basis of the ability for the macromolecular chains to associate via the pendant carboxylic acids, and of the high global symmetry obtained for this polyacid through the geminal placement of the side substituents.

In the current work, synthetic polyamide nylon fibers were modified via the strategy of surface molecular imprinting to develop enantio-selective adsorbent fabrics for chiral recognition of D-phenyllactic acid (D-PhLA). The nylon fibers were first modified by grafting of polyacrylamide and then the incorporated amide groups were converted into functional amino groups via treatment with NaOCl (Hofmann degradation). The amino-functionalized nylon fibers (Ny-NH 2 ) were interacted with the targeted D-PhLA enantiomer before crosslinking the amino-containing grafted chains with glutaraldehyde crosslinker followed by leashing the template D-PhLA out of the formed surface polymeric matrix by lowering the pH to 1 to finally produce the desired enantio-selective adsorbent fibers DP-Ny. Different instrumental methods such as elemental analysis, Fourier transform infrared spectroscopy, XRD and TGA were employed to examine all the synthetic procedures. SEM was also utilized to observe the morphological appearances of both native and modified nylon fibers. Moreover, the optimum extraction of D-PhLA was found to occur at pH 7. Isotherm studies of the prepared DP-Ny fibers obeyed the common Langmuir linear equation with q m values 130 ± 2 and 75 ± 1 mg g −1 in the case of D-PhLA and L-PhLA, respectively. Furthermore, the enantiomeric resolution of (±)-PhLA racemate was successfully carried out by a column technique with enantiomeric excess reaching approximately 78%.
