Nylon 66 is synthesized by polycondensation of hexamethylenediamine and adipic acid. Equivalent amounts of hexamethylenediamine and adipic acid are combined in water. In the original implementation, the resulting ammonium/carboxylate salt was isolated and then heated either in batches or continuously to induce polycondensation.
Repeating unit of polyphthalamide. Polyphthalamide (aka.PPA, [1] High Performance Polyamide) is a subset of thermoplastic synthetic resins in the polyamide family defined as when 55% or more moles of the carboxylic acid portion of the repeating unit in the polymer chain is composed of a combination of terephthalic (TPA) and isophthalic (IPA) acids.

Nylon 46 (nylon 4-6, nylon 4/6 or nylon 4,6, PA46, Polyamide 46) is a high heat resistant polyamide or nylon. Envalior (formerly DSM) is the only commercial supplier of this resin, which markets under the trade name Stanyl.
Word-mark. Zytel is a trademark owned by Celanese and used to make different high-strength, abrasion, and impact-resistant thermoplastic polyamide formulations, in the family of material more commonly known as nylon.
The company was founded in 1928 by Alex Schulman by selling rubber products from a plant in Akron, Ohio. [2]In 1972, the company became a public company via an initial public offering.
Nylon is a family of synthetic polymers characterized by amide linkages, typically connecting aliphatic or semi-aromatic groups.. Nylons are generally white or colorless [1] [failed verification] [2] [failed verification] and possess a soft texture, with some varieties exhibiting a silk-like appearance.
Polyphenylene oxide (PPO), which is obtained from the free-radical, step-growth oxidative coupling polymerization of 2,6-xylenol, has many attractive properties such as high heat distortion and impact strength, chemical stability to mineral and organic acids, and low water absorption. PPO is difficult to process, and hence the commercial resin ...
