采用分步悬浮聚合法制备了聚二乙烯基苯/聚丙烯酸甲酯（PDVB/PMA）大孔互穿聚合物网络,将其中的聚丙烯酸甲酯用乙二胺氨解,合成了具有疏水/亲水性能的聚二乙烯基苯/聚（N-2-氨基乙基丙烯酰胺）（PDVB/PNAEAM）大孔互穿聚合物网络（IPN）;测定了该树脂的孔结构、含水量、弱碱交换量和溶胀性能;测定了该树脂对水杨酸在不同温度下的吸附等温线,利用热力学函数关系计算出了吸附焓、自由能和熵.推测PDVB/PNAEAM IPN树脂中疏水性的PDVB一网具有疏水作用吸附能力、亲水性的PNAEAM一网具有氢键作用吸附能力.动态吸附及脱附实验表明湿态PDVB/PNAEAM IPN树脂对水溶液中水杨酸的饱和吸附量达到46.1mg/mL.树...

The objective of this work was to develop an adsorption resin for removing aromatic acid contaminations of aqueous environment. The macroporous polydivinylbenzene/poly(methyl acrylate) interpenetrating polymer network was prepared by sequential suspension polymerization method; it was then converted to the hydrophobic-hydrophilic macroporous polydivinylbenzene/poly(N-2- aminoethylacrylamide) interpenetrating polymer network ( PDVB/ PNAEAM IPN) by aminolysis with ethylenediamine. The hydrophobic PDVB part in PDVB/PNAEAM IPN resin has the ability of adsorption through hydrophobic interaction; on...
