As a representative polyoxamide, poly(hexamethylene
oxamide (PA62) was synthesized through ring-opening polymerization of cyclic
oxamide by DuPont as early as 1968 [28, 29].
Rosentsveig, "Intramolecular hydrogen bonds in the sulfonamide derivatives of
oxamide, dithiooxamide, and biuret.
Its purported effect is to "prevent supersaturation of lithogenic substances, control
oxamide (a substance that precipitates stone formation) from the intestine and correct the crystalloid-colloid imbalance.
Then it discusses research done at Muscle Shoals, Alabama, in the 1960s on the synthesis of
oxamide, a potential slow-release nitrogen fertilizer, from hydrogen cyanide (HCN).
1830 Obtained
oxamide by distillation of ammonium oxalate.
It also contains an
oxamide metal-deactivating functionality.
A novel bio-based polyamide, poly(pentamethylene
oxamide) (PA52), with high molecular weight has been prepared from dibutyl oxalate and renewable monomer of 1,5-pentanediamine by a two-step polymerization procedure.
B Shim, Determination of Ag(I) Ion at a Modified Carbon Paste Electrode Containing N,N'-Diphenyl
Oxamide, Bull.
It contains an
oxamide functionality that gives it metaldeactivating properties, according to Gimbarski, who adds that this characteristic is unusual in a HALS.
