BRAINCAKENylon-6,6 and Kevlar
Nylon-6,6 and Kevlar are both polyamides, but their monomers give them very different properties.
Nylon-6,6 is made from hexane-1,6-diamine and hexanedioic acid (or hexanedioyl dichloride). The name comes from the six carbon atoms in each monomer.
n H2N(CH2)6NH2 + n HOOC(CH2)4COOH → [-NH(CH2)6NH-CO(CH2)4CO-]n + (2n − 1) H2O
