Pure X-ray diffraction profiles have been analysed for polyamide (PA) 1010 and added BMI system by means of multipeak fitting resolution of X-ray diffraction. The methods of variance and fourth moment have been applied to determine the particle size and strain values for paracrystalline materials, and the values thus obtained have been compared. The results indicated that both variance and fourth moment of X-ray diffraction line profile' yielded approximately the 'same values of the particle size and the strain. The particle sizes of (100) reflection have been found tO decrease with increasing BMI *** the contrary, the strain values were on the increase.

WAXD and SAXS for PA1010+BMI system have been measured. The results obtained with the help of Ruland and ID EDCF. showed that Wc1x1, the long period L and the thickness of the crystal lamellae do decreased with BMI content at PA10101+BMI system. Comparing both experimental and calculated densitl c values indicated thst the values were of better conformity. Adding BHI into PA1010 caused an increase in *** results from SAXS analysis have also led to the conclusion that a crystal-amorphous interphase could exist in lamellae of Semicrystalline polymers and a three-phase model instead of traditional two-phase model should be used.

The kineties of non-isothermal crystallization of Nylon-1010 has been investigated by using differential scanning calorimetry(DSC), DSC curves were obtained under cooling rate(R): 2. 5, 5, 10, 20, 40K/min. Applying Mandelkern and Ziabicki theories, the values of the Z kinetic parameter and G the kinetic crystalllzab- ility have been determined. Expenents of Avrami obtained in this work decrease with increase of cooling rate and then level off. The experimental results show disagreements with the Ozawa equation.

The structures of Nylon-1010 with different draw ratios have been investigated by using Small-Angle X-ray Scattering(SAXS).It is shown that by using a simple geometrical construction the following structure parameters can be directly derived from the correlation function,the long period(L),the thickness of the crystal amorphous interphase(dtr),the lamellar thickness(do),the“invariant”(Q),the specific inner surface(Os), and the electron density difference between the core of the crystallites and the amorphous matrix(η_ε-η_ω)。
