    Notizen: Irradiated polyamide-1010 (PA 1010) and PA 1010 containing 0.5% (wt) heterogeneous nuclei were studied by ESR, WAXD, DSC and the determination of gel fractions. The fold surface of the lamellae plays an important role in the effects of radiation on crystalline PA1010. The results show that the direct radiation effects on both samples vary, while after being heated to 220°C, the final radiation effects are identical, regardless of the difference in the amount of the fold surface of the lamellae. The post-radiation effects result predominantly from the fold surface.

    Crystal structure of the blend of polyamide 1010 with a bismaleimide by WAXD and SAXS (1996)
    Weinheim : Wiley-Blackwell

    Notizen: The blend polyamide 1010/N,N′-(diphenylmethane-4,4′-diyl)bismaleimide (PA1010/BMI) has been investigated by means of WAXD and SAXS. The results obtained with the help of the Ruland, variance and 1D EDCF analysis showed that the degree of crystallinity (Wc,x) crystallite size (Lhkl), long period (L) and thickness of average crystal lamellae (d) decrease with BMI content. Experimental and calculated density values (ρc) are in good agreement. Addition of BMI to PA1010 causes an increase in structural distortion. The results from SAXS analysis also supported that a crystalline amorphous interphase exists in the lamellae of semicrystalline polymers, so that a three-phase model instead of the traditional two-phase model should be used.
