| 摘 要： | 关于氯化聚乙烯(CPE)或聚氯乙烯(PVC)与乙烯—醋酸乙烯酯共聚物(EVA)共混体系相容性的研究,已有不少报道,其中Coleman等人运用FTIR方法研究了含VA45％的EVA与CPE、PVC的共混体系,测定了该体系的低临界共溶温度(LCST)。一般认为,如果VA含量更低,由于EVA本身的结晶,共混体系将变得难以

| Abstract: | The compatibility in EVA/CPE or PVC was studied by IR spectroscopy. The frequency shifts of the carbonyl stretching vibration near 1739 cm-1 was examined as a function of VA content in EVA, Cl content in CPE(or PVC), blend composition and sample temperature.By comparing with model systems, such as EVA/CCl4, EVA/CHsCCl3 and EVA/CHCl3, the frequency shift observed for the blends was associated mainly with the hydrogen-bonding-like interaction between EVA and CPE (PVC). Based on the temperature dependence of the C = O frequency, the phase separation temperature and its dependence on blend composition were obtained for EVA(VA40%)/CPE(C164%) system. |
