The two most important kinds of nylon are nylon 6,6 and ..

It is used for the synthesis of organic chemicals and surfactants used in detergent, ore floating agent, fabric softener, anti-static agent, germicide, insecticide, emulsifier, anti-caking agent, lubricant and water treatment agent.

As well as polyisocyanates and polyols, the manufacture of polyurethanes needs a variety of other chemicals to control the polyurethane-forming reactions and to create exactly the right properties in the end-product.

Polymer Synthesis of Polystyrene and Nylon-6,6

Students will expand their current knowledge of organic chemistry and be able to write and perform synthesis reactions.

In this study, we developed recombinant Escherichia coli strains expressing Lactococcus lactis subsp. lactis Il1403 glutamate decarboxylase (GadB) for the production of GABA from glutamate monosodium salt (MSG). Syntheses of GABA from MSG were examined by employing recombinant E. coli XL1-Blue as a whole cell biocatalyst in buffer solution. By increasing the concentration of E. coli XL1-Blue expressing GadB from the OD600 of 2–10, the concentration and conversion yield of GABA produced from 10 g/L of MSG could be increased from 4.3 to 4.8 g/L and from 70 to 78 %, respectively. Furthermore, E. coli XL1-Blue expressing GadB highly concentrated to the OD600 of 100 produced 76.2 g/L of GABA from 200 g/L of MSG with 62.4 % of GABA yield. Finally, nylon 4 could be synthesized by the bulk polymerization using 2-pyrrolidone that was prepared from microbially synthesized GABA by the reaction with Al2O3 as catalyst in toluene with the yield of 96 %.

The physical properties, as well as the chemical structure, of a polyurethane depend on the structure of the original reactants, in particular the R1 and the R2 groups. The characteristics of the polyols - relative molecular mass, the number of reactive functional groups per molecule, and the molecular structure - influence the properties of the final polymer, and hence how it is used.

Electrochemical routes for industrial synthesis - SciELO

There is a fundamental difference between the manufacture of most polyurethanes and the manufacture of many other plastics. Polymers such as poly(ethene) and poly(propene) are produced in chemical plants and sold as granules, powders or films. Products are subsequently made from them by heating the polymer, shaping it under pressure and cooling it. The properties of such end-products are almost completely dependent on those of the original polymer.

Nylon can be synthesized by polycondensation
The growth of polymer chains proceeds by condensation reactions between molecules of all degrees of polymerization. Nylon 6,10 is formed at the interface between 2 immiscible solutions made from 6 g sebacoyl chloride and 3 g 1,6-diaminohexane
