Polyamide - PA66 - Nylon

Polyamide-66 (PA66) is a semi-erystalline polymer (poly(hexamethylene adipamide)) synthesized by the polyeondensation of diamine and diaeid. The numbers 66 indicate how many (—CH2—) units occur in the diaeid and the diamine groups. Polyamide (PA) is a well-known material with different commereial names, e.g. Nylon by DuPont, Stanyl by DSM, etc. Polyamides are complex engineering polymers used for a wide range of industrial applications in bulk and fibrous forms. PA66 fibers are used in the moorings of ships, in... [Pg.169]

High molecular weight polyamides are commonly known as nylon. Polyamides are crystalline polymers typically produced hy the condensation of a diacid and a diamine. There are several types and each type is often descrihed hy a number, such as Nylon 66 or Polyamide 66 (PA66). The numeric suffixes refer to the number of carbon atoms present in the molecular structures of the amine and acid respectively (or a single suffix if the amine and acid groups are part of the same molecule).

Varying the monomer composition has produced many different varieties of polyamides. Variations include PA69, PA610, and PA612 (made from HMDA and the 9-, 10-, and 12-carbon dicarboxylic acids, respectively) and Nylon 11 and Nylon 12 (via the selfcondensation of 11-aminoundecanoic acid and lauryl lactam, respectively). These specialty nylons exhibit lower Tj, and lower moisture absorption to one-third or one-fourth that of PA6 or PA66. [Pg.4]
