- Nylons were originally inspired by proteins - both have polyamide linkages along their backbones which are made during the polymerization steps either biologically or synthetically. Most nylons have straight hydrocarbons between these linkages while the proteins have 20 different side arms, one for each of the 20 essential amino acids. If you were to prepare a nylon using α-amino carboxylic acids, you would end up with a nylon-2, a very rare entity indeed. Here's the structure of protein and nylon-6 for comparison:
- 50+% market share is pretty rare, but does occur if you have a really good product. Two examples that I ran across recently were toothbrushes and sunscreen. In both cases, the 50+% market share was actually that of suppliers to the end product, rather than the end products themselves. Specifically, half the tooth brushes are made on machines made by the Zahoransky Group in Germany and half the sunscreens sold have UV absorbers made by BASF.
