【摘要】 本文叙述了脉冲NMR的基本原理及其在高聚物辐射化学方面的应用情况。以聚二甲基硅烷(PDMS)和聚异丁烯(PIB)为例,详细介绍了利用脉冲NMR研究高聚物辐射交联和裂解行为的方法。对该技术在聚乙烯(PE),聚氧化乙烯(PEO)等体系中的应用情况,也做了简单介绍。更多还原

【Abstract】 This paper described the basic principle of pulsed NMR and itsapplication in the radiation chemistry of polymer. To take polydimethylsiloxane andpolyisobutylene as examples, we illustrated how to use this method to study thebehaviour of radiation induced crosslinking and fracture of polymer. Moreover, thecondition of application of this method to polyethylene, poly (ethylene oxide) andother systems has been briefly described.更多还原
