From X-ray diffraction patterns of uniaxially oriented fibers

the crystal structure of Nylon-1010 was determined. The Nylon-1010 crystallizes in the triclinic system

with lattice dimensions: a = 4.9A

b = 5Ak

c = 27.8A

α = 49°

β = 77°

γ= 63.5°

the unit cell contains one monomeric unit and the space group is PI. The degree of crystallinity of polymer was determined as about 60%

using Ruland's method.SAXS has been used to investigate the crystalline lamellar thickness

long periods

transition zones

the specific inner surface andan electron density difference between the crystal-line and amorphous regions for Nylon-1010

the analysis of data was based upon the one-dim-ensional electrondensity correlation function (EDCF).
