摘要: 在甲苯和C9~C13醇混合物作稀释剂存在下,以偶氮二异丁腈作引发剂,用悬浮聚合法由间-苯二甲酸二烯丙酯、二乙烯苯和丙烯腈制备了一系列多孔共聚物,改变单体的摩尔比获得了不同极性的气相色谱柱填料,而共聚物小球的多孔结构主要决定于稀释剂的数量和组成,测定了小球的物理化学性能和气相色谱性能,并用改进的McReynolds极性标度评价其极性,通过实例展示这种色谱固定相的优良选择性。

Abstract: A series of porous copolymers from diallyl m-phthalate, divinylbenzene and acryloni-trile were prepared by suspension polymerization in the presence of a mixture of toluene and C9~G13 alcohols as a diluent, using azo-bis-isobutyronitrile as an initiator.By changing the molar fractions of the monomers, the GCcolumn packing materials of different polarities have been obtained.The porous structure of the polymeric beads is mainly dependent on the amount and constituents of the diluent.The physicochemical and gas chromatographic properties of these new ester-containing polymeric beads were determined and the polarities were evaluated by means of modified McReynolds polarity scale.The excellent selectivity of these GCstationary phases is well documented through several examples.
