Nylon 6,10 is another important nylon with very similar properties.

Amides are formed by the condensation reaction between a carboxylic acid and an amine (primary or secondary amines, or ammonia). Water is formed as a byproduct from the carboxylic acid –OH and the amine –H (Scheme 5). It could be very easy to understand amide formation if you recall the ester formation reaction (Scheme 3). However, unlike ester formation, the amide reaction equilibrium is highly unfavorable for the synthesis of products because a competing acid-base reaction occurs between a carboxylic acid and amine. Many methods are thus used to drive the reaction to the right. For example, either acid chloride or acid anhydride is used as a more reactive carboxylic acid derivative to prepare amides. In a similar way, the amide bond is formed between the carbonyl carbon and the amine nitrogen while the –Cl joins –H to form HCl (when using acid chloride) or the RCOO– joins –H to form a carboxylic acid (when using acid anhydride) (Scheme 5). In addition to learning these concepts in lecture, students engage in laboratory experiments such as the synthesis of nylon from adipoyl chloride and hexamethylemediamine that serve as good strategies to reinforce the concept of amide formation and solidify student understanding of this reaction.

T1 - Templated synthesis of nylon nucleic acids and characterization by nuclease digestion

AB - Nylon nucleic acids containing oligouridine nucleotides with pendent polyamide linkers and flanked by unmodified heteronucleotide sequences were prepared by DNA templated synthesis. Templation was more efficient than the single-stranded synthesis; coupling step yields were as high as 99.2%, with up to 7 amide linkages formed in the synthesis of a molecule containing 8 modified nucleotides. Controlled digestion by calf spleen phosphodiesterase enabled the mapping of modified nucleotides in the sequences. A combination of complete degradation of nylon nucleic acids by snake venom phosphodiesterase and dephosphorylation of the resulting nucleotide fragments by bacterial alkaline phosphatase, followed by LCMS analysis, clarified the linear structure of the oligo-amide linkages. The templated synthesis strategy afforded nylon nucleic acids in the target structure and was compatible with the presence heteronucleotides. The complete digestion procedure produced a new species of DNA analogues, nylon ribonucleosides, which display nucleosides attached via a 2′-alkylthio linkage to each diamine and dicarboxylate repeat unit of the original nylon nucleic acids. The binding affinity of a nylon ribonucleoside octamer to the complementary DNA was evaluated by thermal denaturing experiments. The octamer was found to form stable duplexes with an inverse dependence on salt concentration, in contrast to the salt-dependent DNA control.

Polymerization of Nylon 6 and Nylon 6,10 - pslc

We have seen the formation of the polyamide nylon-6,6 and the polyester PET.

Plastics make up a major category of the polymer field. The world plastics market was about 622 billion pounds in the year 2014. The plastics industry is the third largest manufacturing industry in the United States. In 2014, more than $427 billion in plastic goods were shipped. Most of these materials are a synthetic commodity and engineering resins and the major types are listed below. From Nylon 6/6 testing, to ABS and PET testing, Polyhedron has the capbilities to peform thousands of plastics tests. Polyhedron Laboratores has been performing an extensive number of tests for over 40 years.

In this polymer, all amide bonds lie in the same direction, but this does not cause a major divergence from the properties of nylon 6,6.

Nylon 6/6 is a semi-crystalline polyamide composed of polyhexamethyleneadiptimide. Nylon 6 and Nylon 6/6 are the two most common grades of nylon manufactured. The number refers to the number of carbons that occur on each side ofthe amide groups, or nitrogen atoms.

Many students (including the author) take a one-semester fundamental chemistry lecture and laboratory course (CHEM 102) that surveys the basics of organic chemistry and biochemistry (Van Lanen, 2000). It is organized around topics of organic chemistry, but with some biological perspective (Miner, 1948; Isom, 2006). This course is often required for students in health-oriented programs, especially the nursing program (at the University of South Carolina, Chemistry 102 is required in the nursing curriculum, as shown ), and it may also serve as a laboratory science for students in other fields of study (Price, 1976; Mamantov and Wyatt, 1978). Emphasis for this course is often placed on selected principles relevant to the understanding of human biological functions and related medical aspects. However, this course is often seen by students as a difficult and professionally irrelevant barrier in pursuing a career in medicine or nursing. Moreover, even though knowing detailed chemical properties of organic molecules is not a main objective for this course, students are required to comprehend some basic organic reactions, especially those closely related to biochemical processes of the human body. Some typical examples are the oxidation of an alcohol, the formation of a disulfide bond, carboxylic acid and amine dissociation, esterification, and amide formation. However, learning organic reactions for non-science major students has often been unpleasant (Rowe, 1983; Burgess and Bino, 1988).

The resulting block copolymers, presumably the structure of nylon 6-SBR-nylon 6, were confirmed from their IR spectra.
