摘要： 用扭摆分析研究了EVA树脂和PVC共混体系中,VA含量和共混物组成对其相容性的影响.共混的两组分的分子间相互作用对其相容性有关键的影响.用FTIR测定羰基伸缩振动谱带的位移,可表征EVA-PVC分子链间的相互作用.

Abstract: TPAand FTIRstudies of blends of EVAcopolymers and PVCare Presented in this paper. The results demonstrate that the blends of the EVAcontaining 34-35% VAand PVCare incompatible and the 75/25 and 50/50 blends of the EVAcontaining 70% VA/PVCexhibit single phase Tg while the 25/75 blend exhibits two mixed EVA/PVCphases.The shifts of the vs(C=O) in FTIRspectra indicate there are specific inter-molecular interactions between the EVA-70 and PVCmolecular chalnsr egardless of one or two mixed EVA/PVCphases.
