For example, polyfhexamethylene oxamide) (PA62) and polyfnonamethylene oxamide) (PA92) have saturated water absorptions of 2.7 and 1.3 wt% [2], respectively, which are about one fourth and one eighth of that of polycaprolactam (PA6) (10.7 wt%).
In this work, a novel bio-based POA, poly(pentamethylene oxamide) (PA52), with high molecular weight is prepared from dibutyl oxalate (DBO) and renewable monomer of PDA by a two-step polymerization method (precondensation in solution and postcondensation in the solid state).
Bio-based poly(pentamethylene oxamide) (PA52) with high relative viscosity ([[eta].sub.r] = 3.17) is synthesized by a solution/solid-state polymerization procedure using DBO and bio-originated PDA as monomers.
HA-B-AO has the metal-deactivating oxamide group of HA-R100 as an additional stabilizing functionality in the middle of the structure.
In this paper we report the crystal s tructure of a monoclinic poly morph of NN'-bis (2-pyridyl) oxamide as well as its DNA -binding property.
The results showed that the ExtPEA(0, m)s were mainly constituted with the diester oxamide alternating units.
the peaks at 4.09 and 3.38 ppm corresponded to l-[CH.sub.2]- and 2-[CH.sub.2]-hydrogens in the alternating oxamide adipate units (I).
the strong absorption peaks at 3401 and 3306 [cm.sup.-1) were assigned lo ihe N-H stretch-ing vibration of the amide groups in the alternating oxamide adipate units (I) or the esleramide unils (II) fonned by the esier-amide interchanging reaction, and the amide groups in the lerephihalamide dieslers units (III) fonned in the chain extension between the HOOC- terminal groups of the PrePEA(0.
Pryde and Chan (9) and Chan (10) suggest that hydrazine compounds slightly out perform oxamide compounds as metal deactivators when infrared spectra are compared or oxygen uptake is measured.
