摘要
本文利用热分析仪通过DSC对所合成的中高分子量聚乙二醇(PEG)进行了熔融过程的热力学参数(Tm、△Hm)测定,得出了其随分子量变化的规律,并利用其在氧化裂解过程中的热失重曲线(TG)进行动力学参数(E、n、A)测定和热稳定性的研究。
Thermodynamic parameters(Tm,△Hm.)of the medium-high molecular weight polyethylene glycols(PEG)synthesised in our lab are determined with their DSC curves.Somethermokinetic parameters such as E,n,A and thermostability are also determined and revealed.respectively with their TG curves when the samples undergo the oxidative cracking process.
