反气相色谱法(IGC)是测试高聚物结构变化较为新的方法之一,具有较高的灵敏度和可靠性。已有人用于共混聚合物的相分离研究. 聚乙烯甲醚(PVME)和聚苯乙烯(PS)是一典型的非晶一非晶型共混相容体系,有关该体系的相分离研究已有一些报道。本工作拟用反气相色谱法研究其相分离过程的保留特性,旨在进一步探讨相分离的本质和反气相色谱法对共混聚合物相分离研究的适用性。
Anti-gas chromatography (IGC) is one of the more recent tests for the structural changes of polymers, with high sensitivity and reliability. Phase separation studies have been used to blend polymers.PVM and PS are typical amorphous-amorphous hybrid compatibilized systems, and phase separation studies on this system There have been some reports. This work intends to use anti-gas chromatography to study its phase separation process retention characteristics, to further explore the nature of phase separation and anti-gas chromatography on polymer blend phase separation of the applicability.
