    Gamma-radiation damage to polyamide-1010 crystal structure (1994)
    New York, NY [u.a.] : Wiley-Blackwell
    Polymer International 35 (1994), S. 335-359

    Notizen: Radiation effects on polyamide-1010 specimens having various states of aggregation were studied using wide angle X-ray diffraction, electron spin resonance, calorific and sol measurement techniques. Experimental results indicated that chain crosslinking and scission of the irradiated polyamide-1010 occurred mainly in the amorphous region and on the crystal surface. The radiation-induced crystal damage and amorphotization started from the crystal surface (or interface) and extended into the inner portion of the crystal with increasing radiation dose. It is believed that the interface between crystalline and amorphous regions was the main region wherein free radicals were trapped.

    Influence of the fold surface of the lamellae on radiation effects - research on irradiated polyamide-1010 containing heterogeneous nuclei (1996)
    New York, NY [u.a.] : Wiley-Blackwell
    Polymer International 39 (1996), S. 295-302 
    Details
    ISSN: 0959-8103
    Schlagwort(e): heterogeneous nuclei ; crystalline-amorphous interphase ; PA 1010 ; radiation effects ; post-radiation effects ; fold surface of the lamellae ; Chemistry ; Polymer and Materials Science
    Quelle: Wiley InterScience Backfile Collection 1832-2000
    Thema: Chemie und Pharmazie , Maschinenbau , Physik
    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.
