The two compounds form a salt, known as nylon salt, an exact 1:1 ratio of acid to base. This salt is then dried and heated under vacuum to eliminate water and form the polymer. In another approach, a compound containing an amine at one end and an acid at the other is polymerized to form a chain with repeating units of (-NH-[CH2]n-CO-)x.
Oct 26, 2018 · Nylon is made through a chemical process called ring opening polymerization, in which a molecule with a cyclic shape is opened and flattened.Other forms of the material are made through the chemical reaction between two monomers: adipoyl chloride and hexamethylene diamine.

Although 1.2mm nylon muscle were able to carry a significantly greater amount of weight, the contraction percentage was less than the 0.6mm nylon muscles with the 1.2mm family contracting on average 4.85% and the 0.6mm family contracting on average 6.14%.
Nylon is a polymer you can make yourself in the lab.A strand of nylon rope is pulled from the interface between two liquids. The demonstration sometimes is called the ‘nylon rope trick’ because you can pull a continuous rope of nylon from the liquid indefinitely. Close examination of the rope will reveal that is is a hollow polymer tube.

Nylon 6 will form uninterrupted H-bonded sheets with mixed directionalities, but the β-sheet wrinkling is somewhat different. The three-dimensional disposition of each alkane hydrocarbon chain depends on rotations about the 109.47° tetrahedral bonds of singly bonded carbon atoms.
One reason there’s a family of nylons is because the original and most common form of the material, nylon 6,6, was patented by E.I. du Pont de Nemours & Company (DuPont™), the US firm where it was invented, so rivals such as German chemical giant BASF had to come up with alternatives. Another reason is that the different kinds of nylon have
