DSC在二端羟基共聚醚与甲苯二异氰酸酯聚合反应历程的研究
二端羟基共聚醚 DSC
2009/11/30
本文运用DSC研究二端羟基共聚醚(PE)与甲苯二异氰酸酯(TDI)的聚合反应历程后认为:运用DSC研究其聚合反应历程是一个简单准确的方法;提出了该反应的化学计量为PE+2TDI→产物,且服从一级反应动力学,具有活化能Eα=61.7KJ/MOL,其反应机理可用在PE与TDI之间形成一个活泼络合物中间体加以解释。本文研究关于二端羟基共聚醚与甲苯二异氰酸酯的反应,该反应在恒温情况下,由示差扫描量热仪(D...

SAXS and DSC study of co-crystallisation of low molecular-weight PEO fractions in polymer blends
PEO/PEO blends PEO/PEO-b-PPO-b-PEO blends SAXS DSC
2009/2/6
This study is aimed at a better understanding of co-crystallisation phenomena in PEO/PEO and PEO/PEO-b-PPO-b-PEO blends in the course of crystallisation. Simultaneous real-time SAXS measurementsand th...
