异氰尿酸三烯丙酯交联共聚物的合成及其色谱性能的研究(Ⅰ)

Studies on the Synthesis and Chromatography Properties of Copolymers Crosslinked with Triallyl Isocyanurate

用异氰尿酸三烯丙酯作交联剂,以醋酸乙烯酯为单体,合成了交联共聚物,测定了它们的比表面积、平均孔径、孔容及溶胀性能,确定了合成的最佳条件;同时把共聚物作为气相色谱固定相,考察了其柱效、峰对称性及分离度等性能,该共聚物可快速分离烷烃、芳烃、醇等。

The copolymer were synthesized from vinyl acetate and triallyl isocyanurate under conventional conditions. Their specific surface area, average pore radius, pore volume and swelling capacity were determined. At the same time the copolymers were used as a stationary phase for gas chromatog-raphy and the column effeciency, peak symmetry and separating size were investigated. They can be used for rapid separation of a few mixtures which are separated difficultly, we expect that they will be used wildely.
