疏水/亲水性大孔聚二乙烯基苯/聚丙烯酰乙二胺互贯树脂的合成及其孔结构研究

Study on the Preparation and Pore Structure of a Hydrophobic/Hydrophilic Macroporous Polydivinylbenzene/Polyacrylethylenediamine IPN Resin

采用分步悬浮聚合法制备的大孔聚二乙烯基苯／聚丙烯酸甲酯互穿聚合物网络（Interpenetrating polymer networks IPN），经过乙二胺氨解，得到新型疏水／亲水性聚二乙烯基苯／聚丙烯酰乙二胺互穿网络（polydivinylbenzene／poly acrylethylenediamine IPN即PDVB／PAEMIPN）．孔结构研究表明，树脂的平均孔径达8．6～136nm．研究了混合致孔剂中良致孔剂与非良致孔剂的比例、两网质量比以及第二网交联度对树脂孔结构的影响．

A novel hydrophobic/hydrophilic macroporous crosslinked polydivinylbenzene/ polyacrylethylenediamine interpenetrating polymer network（PS/PAEM IPN）resin was prepared by using synthetic polystyrene/polymethylacrylate （PS/PMA） IPN as material. Pore structure parameters of the target product were determined. The study of pore structure shows that average pore diameter is 8.6-13.6 nm. The effect of porogen, mass ratio of the two networks and crosslinking degree of the second networks on the pore structure of the PDVB/PAEM IPN resin was investigated.
