Caprolactam molecule used to synthesize Nylon 6 by ring opening polymerization. Nylon 6 or polycaprolactam is a polymer, in particular semicrystalline polyamide.Unlike most other nylons, nylon 6 is not a condensation polymer, but instead is formed by ring-opening polymerization; this makes it a special case in the comparison between condensation and addition polymers.
Type 6,6 Nylon 101 is the most common commercial grade of nylon, and Nylon 6 is the most common commercial grade of molded nylon. [94] [95] For use in tools such as spudgers, nylon is available in glass-filled variants which increase structural and impact strength and rigidity, and molybdenum disulfide-filled variants which increase lubricity.
Nylon 66 (loosely written nylon 6-6, nylon 6/6, nylon 6,6, or nylon 6:6) is a type of polyamide or nylon. It, and nylon 6, are the two most common for textile and plastic industries. Nylon 66 is made of two monomers each containing 6 carbon atoms, hexamethylenediamine and adipic acid, which give nylon 66 its name. [1] Aside from its superior ...
Nylon 6, or polycaprolactam is a polymer in common use; Nylon 11, or polyamide 11 (PA 11) is a bioplastic polyamide; Nylon 12, a polyamide synthesized from 12-carbon monomers; Nylon 46 (aka nylon 4–6, nylon 4/6 or nylon 4,6, PA46, Polyamide 46), a high heat resistant polyamide; Nylon 4, or polybutyrolactam, a biodegradable nylon; Nylon 1,6 ...
A step-growth copolymer -(-A-A-B-B-) n - formed by the condensation of two bifunctional monomers A–A and B–B is in principle a perfectly alternating copolymer of these two monomers, but is usually considered as a homopolymer of the dimeric repeat unit A-A-B-B. [6] An example is nylon 66 with repeat unit -OC-( CH 2) 4-CO-NH-(CH 2) 6-NH ...
At this discovery, the focus of the project shifted to these filaments and 'Nylon' was the result. [29] On February 28, 1935, Gerard Berchet, under the direction of Carothers, produced a half-ounce of polymer from hexamethylenediamine and adipic acid, creating polyamide 6-6, the substance that would come to be known as Nylon.

Holiday names are usually pretty straightforward. New Year's, Thanksgiving and — perhaps least creatively, the 4th of July — all have origins that are fairly easy to figure out.
Caprolactam (CPL) is an organic compound with the formula (CH 2) 5 C(O)NH. This colourless solid is a lactam (a cyclic amide) of caproic acid.Global demand for this compound is approximately five million tons per year, and the vast majority is used to make Nylon 6 filament, fiber, and plastics.
