Nylon 12

Nylon 12 is a polymer with the formula [(CH₂)₁₁C(O)NH]_n. It is made from ω-aminolauric acid or laurolactam monomers that each have 12 carbons, hence the name ‘Nylon 12’. It is one of several nylon polymers.

Synthesis

Nylon 12 can be produced through two routes. The first being polycondensation of ω-aminolauric acid, a bifunctional monomer with one amine and one carboxylic acid group.

n H₂N(CH₂)₁₁CO₂H → [(CH₂)₁₁CONH]_n + n H₂O

The second route is ring-opening polymerization of laurolactam at 260-300˚C. Ring opening can be carried out by cationic or anionic initiators, although cationic initiators have not been used commercially due to the product being less stable and oxidized relatively quickly in comparison to those produced by activated anionic polymerization (monomer casting). Ring-opening polymerization is the preferred route for commercial production.

Properties

Nylon 12 exhibits properties between short chain aliphatic nylons (e.g., nylon 6 and nylon 66) and polyolefins. At 178-180 °C, the melting point of nylon 12 is the lowest among the important polyamides. Its mechanical properties, such as hardness, tensile strength, and resistance to abrasion, are similar to those of nylon 6 and nylon 66. Low water absorption and density, 1.01 g/mL, result from its relatively long hydrocarbon chain length, which also confers it dimensional stability and an almost paraffin-like structure. Nylon 12 is also chemical resistant and insensitive to stress cracking.

Nylon

Nylon is a generic designation for a family of synthetic polymers, more specifically aliphatic or semi-aromatic polyamides. They can be melt-processed into fibers, films or shapes. The first example of nylon (nylon 66) was produced on February 28, 1935, by Wallace Carothers at DuPont's research facility at the DuPont Experimental Station. Nylon polymers have found significant commercial applications in fibers (apparel, flooring and rubber reinforcement), in shapes (molded parts for cars, electrical equipment, etc.), and in films (mostly for food packaging)

Overview

Nylon is a thermoplastic, silky material, first used commercially in a nylon-bristled toothbrush (1938), followed more famously by women's stockings ("nylons"; 1940) after being introduced as a fabric at the 1939 New York World's Fair. Nylon is made of repeating units linked by peptide bonds and is a type of polyamide and is frequently referred to as such Nylon was the first commercially successful synthetic thermoplastic polymer. Commercially, nylon polymer is made by reacting monomers which are either lactams, acid/amines or stoichiometric mixtures of diamines (-NH₂) and diacids (-COOH). Mixtures of these can be polymerized together to make copolymers. Nylon polymers can be mixed with a wide variety of additives to achieve many different property variations.

Nylon (album)

Nylon is a Greek album by singer Anna Vissi, released in Greece and Cyprus on September 28, 2005, and subsequently in select European countries and Taiwan. The album was released as a DualDisc on October 10, 2005, the first of its kind in Greece, and re-released on May 2, 2006 with the title Nylon: Euro-Edition as a tie-in to Vissi's participation in the Eurovision Song Contest 2006. The album reached Platinum status in less than 24 hours after its release.

Album information

Released in September 2005, Nylon was Anna Vissi's first studio album since the commercially successful 2003 Paraksenes Eikones. Vissi characterized Nylon as her best album so far, with Nikos Karvelas paying a lot of attention to the lyrics of the songs he had written.

Upon release, Nylon went platinum within 24 hours in Greece. In October 2005, the album was released on the DualDisc format, the first ever in Greece, with the title Nylon: DualDisc. The DualDisc version featured bonus songs and as well as special footage from the recording studio.

Nylon (band)

Nylon (now The Charlies) is an Icelandic girl group composed of members Alma Goodman (born Alma Guðmundsdóttir), Camilla Stones (born Steinunn Þóra Camilla Sigurðardóttir) and Klara Elias (born Klara Ósk Elíasdóttir). They are Iceland's most successful singer/songwriter girl-band, producing ten number one singles, three number one studio albums, one number one compilation and one number one DVD in Iceland.

History

2004-2005: 100% Nylon and Góðir Hlutir

The group was formed after auditions in Iceland, which Alma, Camilla and Klara attended. A few weeks after the auditions, Emilia was asked whether she would like to be in the band, and after meeting them, she accepted the offer. The group sings pop music in English and Icelandic. Their first single, "Lög Unga Fólksins" (which means "The Young People's Song" in English), was released in April 2004 and went straight to number one. The group have had huge success in their native country of Iceland: achieving a total of 13 Number 1 singles to date, a TV show about their first summer as a girlband, three chart topping albums, and a book entitled "100% Nylon" (which instantly became a best seller). They have also released a DVD entitled "Nylon Allstaðar", which contained their smash hit TV show as well as other bonus features.
