Acid Chloride Preparative Route for Nylon-6,10, which is often used in the nylon rope trick. The nylon rope trick is a scientific demonstration that illustrates some of the fundamental chemical principles of step-growth polymerization and provides students and other observers with a hands-on demonstration of the preparation of a synthetic polymer.
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.
Waferboard belongs to the subset of reconstituted wood panel products called flakeboards. [1] It is a structural material made from rectangular wood flakes of controlled length and thickness bonded together with waterproof phenolic resin under extreme heat and pressure. The layers of flakes are not oriented, which makes it easier to manufacture.
Caprolactam was first described in the late 1800s when it was prepared by the cyclization of ε-aminocaproic acid, the product of the hydrolysis of caprolactam.World demand for caprolactam was estimated to reach five million tons per year for 2015. 90% of caprolactam produced is used to make filament and fiber, 10% for plastics, and a small amount is used as a chemical intermediate.

The Zytel product line is based mostly on nylon 66, but also includes grades based on nylon 6 as a matrix, long chain nylons such as nylon 610 (if based on at least one renewable monomer they are branded Zytel RS), and copolymers including a transparent resin called Zytel 330.
The wood paneling. The Akai GX- 747 reel-to-reel player. The thick silver knobs that turned a quiet, electric green with a humming, thrumming current that sent every audiophile’s heart racing.
The lower parts of the walls of the 16th century dining hall of St John's College, Cambridge are covered with wood panelling in a linenfold design. An English oak chest with complex linenfold panels. Linenfold (or linen fold ) is a simple style of relief carving used to decorate wood panelling with a design "imitating window tracery", [ 1 ...
