反气相色谱法(分子探针法)对聚烯烃的结晶度的测定是一种有效的方法。这一方法与其它方法不同,不需要假设聚合物的某些性质随结晶度作线性改变,因而对共聚物结晶度的测定特别有利。Guillet 等用溶剂溶解聚丙烯涂覆在色谱担体上,或在低温研磨聚丙烯样品得到的粉末和担体混合,用来填充色谱柱,以一适当的“探针分子”通 Anti-gas chromatography (molecular probe method) for the determination of polyolefin crystallinity is an effective method. This method, unlike other methods, does not require the assumption that certain properties of the polymer vary linearly with crystallinity, and therefore, the determination of the crystallinity of the copolymer is particularly advantageous. Guillet et al., Dissolves polypropylene in solvent to coat the chromatographic support, or mixes the powder and support from the low temperature ground polypropylene sample to fill the column with an appropriate “probe”
