Molecular Formula:(C6H11NO)n Properties:Crystalline solid. Sol in phenol, cresols, xylene, and formic acid. Insol in alc, esters, ketones, hydrocarbons. Film used for implant study. ( CNREA8 Cancer Research. 15 (1955),333. ). Grade:Nylon 66 is a condensation product of adipic acid and hexamethylenediamine developed by Carothers in 1935. Adipic acid is obtained by catalytic oxidation of cyclohexane. Nylon 6 is a polymer of caprolactam, originated by I. G. Farbenindustrie in 1940. Nylon 4 is based on butyrolactam (2-pyrrolidone); its tenacity, abrasion resistance, and melting point are said to be about the same as for the 6 and 66 grades. It has excellent dyeability. Nylon 610 (TM “Tynex”) is obtained by condensation of sebacic acid and hexamethylenediamine, and nylon 11 (TM “Rilsan”) from castor bean oil (developed in France). Nylon 12 (also called “Rilsan” 12) is made from butadiene, also by a French process involving photonitrosation of cyclododecane by actinic light from mercury lamps. Its properties are similar to those of nylon 11. Nylon 9 can be made from 9-aminononanoic acid, present in soybean oil. It has properties specifically desired in metal coatings and electrical parts; higher electrical resistance than 6 and 66 absorbs less moisture and has better distortion resistance. Use:Tire cord; hosiery; wearing apparel component; bristles for toothbrushes, hairbrushes, paint brushes (nylon 610); cordage and towlines for gliders; fish nets and lines; tennis rackets; rugs and carpets; molded products; turf for athletic fields; parachutes; composites; sails; automotive upholstery; film; gears and bearings; wire insulation; surgical sutures; artificial blood vessels; metal coating; pen tips; osmotic membranes; fuel tanks for automobiles. AvailableForms:Monofilaments, yarns, bristles, molding powders, rods, bars, sheets. Microcrystalline nylon is now available.
