摘要
使用荷兰菲利浦公司提供的PW-1700自动粉末衍射仪及其Kratky小角散射体系附件,进行熔融辐照交联结晶聚乙烯的研究,从而得到了长周期随辐照剂量变化的关系,发现其熔融结晶是以Fischer固化模型为主。
The crystal structure of polyethylene which is irradiated by γ-rays in heir melting states was studied by means of small angle X-ray scattering(SAXS) method. The results show that the more radiation dose irradiating PE, the smaller the lamellar thinkness is. And consequently,the crystallization of flexible chain polymers from the rubbery state or from the melt does not proceed by chain folding, the solidification model of fischer is a much more appropriate physical picture for the crystallization process from molten state.
