1.6- Hexanediamine, polymer from synthesis

The repeating units in nylon 66 and in most step reaction polymers consist of residues from both reactants. The following equation shows the synthesis of nylon 66 in this case the reactants are a dicarboxylic acid (adipic acid) and a diamine (1,6-hexanediamine). 

The synthesis, characterization, and properties of a series of PEAs obtained from L-malic acid, 6-aminohexanol, and 1,6-hexanediamine, in which the hydroxy side group of malic acid was protected as methyl ether, have been studied [63]. Aregic and isoregic polymers were obtained and, furthermore, the ester-amide ratio was varied (i.e., from 1 50 to 1 1). AU studied PEAs were semicrystalline with T decreasing with the...
