NNRTI medication: Causes the majority of skin rashes, with nevirapine rashes being the most severe. Women are at a particular risk of developing nevirapine rashes.
Nylon was the first commercially successful synthetic thermoplastic polymer. Commercially, nylon polymer is made by reacting monomers which are either lactams, acid/amines or stoichiometric mixtures of diamines (-NH2) and diacids (-COOH). Mixtures of these can be polymerized together to make copolymers.
Polyamides - Nylon: Polyamides such as nylon are also condensation polymers. The formation of a polyamide follows the same procedure as in the synthesis of a simple amide. Again, the only difference is that both the amine and the acid monomer units each have two functional groups - one on each end of the molecule.
