Nylon 6, 6 is a linear condensation polymer made from hexamethylene diamine and adipic acid. Nylon possesses many properties that make it a very useful fiber in many applications. The resulting nylon gets a name based on the number of carbon atoms that separate two aminesand two acidic groups. Nylon 6 was developed in an attempt to reproduce the properties of nylon 66 without violating the patent. The majority of nylons tend to be semi-crystalline and are generally very tough materials with good thermal and chemical resistance. UNITIKA Nylon 6 General Properties. C. Reimschuessel,J.

Math. In nylon 6,6, R' = 6C and R = 4C alkanes, but one also has to include the two carboxyl carbons in the diacid to get the number it donates to the chain. Nylon fiber is very responsive and resilient as well as relatively resistant to heat, UV rays and chemicals. Nylon is a generic name for a family of synthetic polymers, more specifically, aliphatic or semi-aromatic polyamides in which at least 85% by weight of the amide-linkages (-CO-NH-) are attached directly to two aliphatic groups. The term nylon points towards a polymer family known as linear polyamides. Nylons are typified by amide groups (CONH) and encompass a range of material types (e.g. D. C. Prevorsek andW. Macromol. 15 (1966) 263. Nylon is used in the production of film and fibre, but is also available as a moulding compound.
