Porous substrates comprising acrylonitrile polymer or copolymer cores and a hydrolyzed surface, with low conversion to amide groups and substantially no formation of imide or carboxyl groups on said surface. The substrates and functionalized derivatives thereof, are useful in highly selective chromatographic separations.
由丙烯腈聚合物或共聚物芯和水解表面组成的多孔基底,酰胺基转化率低,表面基本不形成酰亚胺或羧基。这些基材及其官能化衍生物可用于高选择性色谱分离。
