I. Gachard et al., SYNTHESIS AND CHARACTERIZATION OF RANDOM AND REGULAR L-LYSINE-BASED POLYAMIDES, Macromolecular chemistry and physics, 198(5), 1997, pp. 1375-1389
This paper deals with the synthesis of polyamides based on the natural
diamine, L-lysine, on the one hand, and diacids, adipic or glutaric,
on the other hand. They were obtained by polycondensation of active di
esters, pentachlorophenyl and pentafluorophenyl esters. L-Lysine being
non-symmetrical, aregic (random) and syndioregic (''head-to-head, tai
l-to-tail'') poly(adipoyl-L-lysine)s and poly(glutaroyl-L-lysine)s wer
e obtained with molecular weights higher than 15000; isoregic (''head-
to-tail'') poly(adipoyl-L-lysine)s and poly(glutaroyl-L-lysine)s were
prepared with lower molecular weights.
