Even earlier, he had been involved in the development of Neoprene\u00ae, a synthetic rubber that is not only used for thermally insulating sports textiles, but has also found its way into numerous technical applications in the form of cable sheathing, hoses, and sponge rubber seals.<\/p>\n<figure id=\"attachment_3431\" aria-describedby=\"caption-attachment-3431\" style=\"width: 280px\" class=\"wp-caption alignleft\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-3431\" title=\"Wallace Carothers, inventor of nylon\" src=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2019\/04\/Wallace-Carothers.jpg\" alt=\"Wallace Carothers\" width=\"280\" height=\"356\" srcset=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2019\/04\/Wallace-Carothers.jpg 300w, https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2019\/04\/Wallace-Carothers-236x300.jpg 236w\" sizes=\"(max-width: 280px) 100vw, 280px\" \/><figcaption id=\"caption-attachment-3431\" class=\"wp-caption-text\">Wallace Carothers, inventor of nylon | \u00a9 Cmclen commons.wikimedia.org<\/figcaption><\/figure>\n<p style=\"text-align: justify;\">Carothers also recognized the great potential of nylon, which can be spun directly from a low viscosity polymer solution into an elastic filament.<\/p>\n<p style=\"text-align: justify;\">As early as 1938, the new plastic nylon was introduced to the US market by DuPont with a large scale advertising campaign under the slogan: \u201cA better fiber for a better life.\u201d<\/p>\n<p style=\"text-align: justify;\">During the war years, nylon in the United States was reserved exclusively for military use. It was employed for parachutes, parachute cords, and flight suits, thus replacing silk, which had previously been sourced primarily from Japan.<\/p>\n<div style=\"clear: both;\"><\/div>\n<h2><span class=\"ez-toc-section\" id=\"Two_related_polymers_nylon_and_Perlon\"><\/span>Two related polymers: nylon and Perlon<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: justify;\">Carothers produced his new plastic from the two components adipic acid and hexamethylenediamine. Adipic acid is a dicarboxylic acid (hexanedioic acid), while hexamethylenediamine is, as its name suggests, a diamine. The carboxyl group (\u2013COOH) reacts with the amino group (\u2013NH<sub>2<\/sub>) to form a peptide bond (\u2013NH\u2013CO\u2013), which represents the basic structural unit of all polyamides.<\/p>\n<p style=\"text-align: justify;\">Within the polymer, the two monomer components are arranged alternately, forming long polymer chains. Instead of the adipic acid and hexamethylenediamine used by Carothers, other monomers can also be employed. In 1938, the German chemist Paul Schlack (1897 1987) succeeded in producing Perlon, which is related to nylon, from \u03b5 caprolactam. When heated, the ring shaped \u03b5 caprolactam is converted into \u03c9 aminocaproic acid (chemically: \u03c9 aminohexanoic acid), which has a carboxyl group at one end and an amino group at the other. It is therefore described as bifunctional and can react, so to speak, \u201cwith itself\u201d to form long chain polyamides.<\/p>\n<p><center><a href=\"https:\/\/www.rct-online.de\/en\/fasteners\/bushings\/30557\/bushing-made-of-pa-m3-m5\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-3464 size-full\" title=\"Bushing made of PA (M3 M5) | Material: PA 6 (polyamide 6)\" src=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2019\/04\/isolierhuelse-aus-pa-m3-m5.jpg\" alt=\"Bushing made of PA (M3 M5) | Material: PA 6 (polyamide 6)\" width=\"300\" height=\"300\" srcset=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2019\/04\/isolierhuelse-aus-pa-m3-m5.jpg 300w, https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2019\/04\/isolierhuelse-aus-pa-m3-m5-150x150.jpg 150w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a> <a href=\"https:\/\/www.rct-online.de\/en\/fasteners\/washers-and-rings\/30451\/washer-made-of-pa-oe-2.2-20.5\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-3465 size-full\" title=\"Washer made of PA (\u00d8 2.2 20.5) | Material: PA 6 (polyamide 6)\" src=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2019\/04\/unterlegscheibe-aus-pa-o-2-2-20-5.jpg\" alt=\"Washer made of PA (\u00d8 2.2 20.5) | Material: PA 6 (polyamide 6)\" width=\"300\" height=\"300\" srcset=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2019\/04\/unterlegscheibe-aus-pa-o-2-2-20-5.jpg 300w, https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2019\/04\/unterlegscheibe-aus-pa-o-2-2-20-5-150x150.jpg 150w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/center><\/p>\n<p style=\"text-align: justify;\">Both plastics are thermoplastics and exhibit similar material properties.

According to this standard, PA is the abbreviation for all polyamides, followed by the number of carbon atoms in the monomers. If a bifunctional monomer is used, as in the case of Perlon based on \u03c9 aminohexanoic acid with six carbon atoms, the abbreviation is PA 6. If, on the other hand, a dicarboxylic acid reacts with a diamine, as is the case with nylon, the carbon atoms of both monomers are counted and listed consecutively. Nylon therefore has the official designation PA 6.6. Occasionally, though not in accordance with the DIN standard, the dot is omitted and PA 66 is used instead. Less common is the replacement of the dot with a slash (PA 6\/6).<\/p>\n<figure id=\"attachment_3453\" aria-describedby=\"caption-attachment-3453\" style=\"width: 600px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-3453 size-full\" title=\"Label for clothing\" src=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2019\/04\/etikett-bekleidung.jpg\" alt=\"etikett-bekleidung\" width=\"600\" height=\"400\" srcset=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2019\/04\/etikett-bekleidung.jpg 600w, https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2019\/04\/etikett-bekleidung-300x200.jpg 300w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><figcaption id=\"caption-attachment-3453\" class=\"wp-caption-text\">\u00a9 Anna Reich stock.adobe.com<\/figcaption><\/figure>\n<p style=\"text-align: justify;\">In addition to nylon and Perlon, other polyamides such as PA 11 or PA 12, the lightest of the polyamide plastics, have also gained economic importance. PA 11 is based on \u03c9 aminoundecanoic acid with eleven carbon atoms, which is obtained from ricinoleic acid, the main component of castor oil derived from castor beans. PA 11, with the trivial name Nylon 11, is therefore regarded as a bioplastic. Its main area of application is the coating of pipelines, and it is marketed under the trade name Rilsan\u00ae.<\/p>\n<p style=\"text-align: justify;\">The starting material for PA 12 is \u03c9 aminododecanoic acid, whose twelve carbon atoms give Nylon 12 its name. The properties of PA 12 are similar to those of PA 6 and PA 6.6; however, its melting point of less than 180 \u00b0C is significantly lower than that of all other commercially available polyamides.<\/p>\n<blockquote>\n<p style=\"text-align: justify;\">PA 12 is used both for corrosion protective coatings on metals and for aroma tight food packaging. It is marketed under the trade name Grilamid\u00ae.<\/p>\n<\/blockquote>\n<p style=\"text-align: justify;\">If one of the monomers contains an aromatic component, this is indicated by an additional abbreviation. For example, \u201cT\u201d stands for terephthalic acid, and PA TT refers to the poly(p phenylene terephthalamide) formed from the monomers terephthaloyl chloride and phenylenediamine. Its trivial name is Kevlar\u00ae, a particularly rigid, tear resistant, and temperature resistant plastic used in bulletproof vests, safety helmets, and aircraft components.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Fibers_or_granules\"><\/span>Fibers or granules<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: justify;\">Nylon and Perlon remain the most widely used polyamides today.
