将醋酸乙烯酯与三烯丙基异氰尿酸酯共聚物进行皂化制得含有羟基和羧基盐的共聚物以增强共聚物的亲水性,用作气相色谱固定相。考察了不同交联度对皂化反应的影响,测定了皂化后共聚物的结构参数及溶胀性能,并对该固定相的色谱性能进行评价。
The copolymer of vinyl acetate and triallyl isocyanurate is saponified to produce a copolymer containing hydroxyl and carboxyl salts to enhance the hydrophilicity of the copolymer for use as a stationary phase for the gas chromatograph. The effects of different degree of crosslinking on the saponification reaction were investigated. The structural parameters and swelling properties of the copolymer were determined. The chromatographic properties of the copolymer were also evaluated.
