【摘要】 本文通过反相色谱法测定PS/PMMA,PS/PVC,以及PS/P(S-co-α-MeS)共混物等样品的Tg来判断其热力学相容性的情况,结果前两对共混物测得两个Tg为热力学不相容体系,后者只测得一个Tg为热力学相容体系。并且与DSC等法进行对比,证明上述反相色谱法对共混物相容性的研究有着较高的灵敏度。更多还原

【Abstract】 The compatibility of amorphous polymer blends can be in vestigated by determination of glass transition with inverse gas chromatography(IGC). Two glass transitions for the PS/PMMA and PS/PVC blends and one glass transition for the PS/P (S-co-α-MeS) blend have been determined by IGC. From which we can infer that the PS/PMMA and PS/PVC blends are thermodynamic uncompatibility and the PS/P (S-co-α-MeS) blend is thermodynamic compatibility.更多还原
