E. , methine carbons were spit into the two components with inclusion of PVP to system. The above observation were responsible for the formation of intermolecular hydrogen bonding interactions. The proton spin-lattice relaxation time T〓, T〓 in the laboratory and the rotating frame were measure as a function of the blend composition. In view of the relaxation parameters, it is concluded that the Phenoxy and PVP chain are intimately mixed on the scale of 20-30A.
采用反转-回复法,我们测定该体系的T〓,T〓值的测定进一步支持,根据Tg判断的相容性。T〓ρ的研究结果表明,该体系在分子水平上是相容的,根据自旋扩散过程,估算该体系的相容性尺度为20-30〓,实验的1/T〓ρ组成关系同理论的线性关系比较呈负偏差,表明共混改变了组分在体系中的混合状态。
