From Wide-Angle X-ray Scattering (WAXS) pattern of uniaxially orientated fibers, the crystal structure of Nylon-1010 was determined. The Nylon-1010 crystallizes in the triclinic system, with lattice dimensions: a=4.9A, b=5.4A, c=27.8, α=49 °, β=77 °,γ=63.5 °, the unit cell contains one monomeric unit and the space group is P. The degree of crystallinity of polymer was deter mined as about 60%, using Ruland's method.The structures of Nylon-1010 with different draw ratio have been investigated by using Small-Angle X-ray Scattering (SAXS).The results indicate that the draw ratio of samples has a significant effect on microstructure of Nylon-1010.The long period and thickness of amorphous layer obviously increase but the invariant,average lamellar and interphase zone show almost independent of draw ratio,long period increases because amorphous layer increases with draw ratio.The electron density fluctuation values increased with draw ratio,but inner surface Os is drecreased.
