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 distortion.The 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.展开更多

The results revealed that the maximum values of Q, I(0), Pmax(Z), dtr. Rg and Wcx were obtained nearby T=175℃ for PA-1010 samples with various annealing treatment. The higher degree of the crystallinity, the greater values of all the structural paranleLers of the aggregated state for PA-1010 samples were.展开更多
