摘要：多检测ＧＰＣ／ＳＥＣ 在高分子表征中可获得比普通单检测ＧＰＣ 丰富得多的重要信息，因而受到学术界和工业界的广泛重视。详细介绍了ＧＰＣ／ＲＩ／ＲＡＬＬＳ／ＤＶ 多检测技术的检测原理，并介绍了应用实例。
Novel liquid crystalline polymers of polyacetylenes with comb structure were studied by SEC/RI/RALLS/DV. The relationship between the molecular size and the polymer structure was formulated, and the theta condition of two samples was obtained. Flory′s characteristic ratios C ∞ and unperturbed dimensions (/M) 1/2 were calculated. The effect of the side group size on chain flexibility was discussed. The results show that the technique of SEC/RI/RALLS/DV is a useful means for characterizing the novel liquid crystalline polymer of polyacetylenes with comb structure, which can not be effectively characterized by conventional SEC.
