peer agreement (net): +1a Poliamid Explanation: polyamide Synthetic (nylon) and natural (protein) polyamides are made by polymerizing amino acids and lactams. Synthetic polyamides were first developed by Wallace H. Carothers at DuPont in 1938. They are thermoplastic resins that are characterized by their high degree of toughness, strength and durability along with their resistance to chemicals and heat. They are manufactured as bristles, fibers, molding powders, sutures, adhesives and coatings. The most important examples of polyamides are the various kinds of nylon. See also aramid. -------------------------------------------------- Note added at 2002-10-23 01:09:46 (GMT) -------------------------------------------------- Correction: A Polyamide |

peer agreement (net): +4New York LONdon Explanation: Nylon The trade name Nylon is often used to refer to a whole class of condensation polymers containing the polyamide linkage. The name Nylon comes from a combination of New York and London, denoting the transatlantic collaboration that took place in its development after it was discovered in the USA in the 1930s. The most common polyamides are manufactured from benzene via cyclohexane and a nitrogen-containing intermediate such as caprolactam or diaminohexane. Polyamides have high strength, abrasion resistance and ease of dyeing, making them suitable for melt-spinning into yarns for the production of nylon stockings, other articles of clothing and carpets. Polyamides are also used in moulded components, for example in cars and sports equipment, and in such applications they are often compounded with fillers, pigments, glass fibre and toughening agents. -------------------------------------------------- Note added at 2002-10-23 05:11:53 (GMT) -------------------------------------------------- http://www.plastics-museum.com/people/scientists/1.htm Reference: http://www.chemical-industry.org.uk/chemfiles/chemfiles.php3... |
