由氯甲基化聚苯乙烯合成了大孔交联聚(对乙烯基苄基苯基醚)树脂(简称为苯基醚树脂), 测定了其对正己烷和水中苯酚的吸附等温线, 计算了吸附焓. 同时, 比较了聚(对乙烯基苄甲醚)、苯基醚树脂、聚(对乙烯基苄基对硝基苯基醚)和聚(对乙烯基苄基对甲基苯基醚)对正己烷中苯酚的吸附性能以及氯甲基化聚苯乙烯和苯基醚树脂对水中苯酚、2,3,5-三甲基苯酚和对硝基甲苯的吸附性能. 结果表明, 苯基醚树脂是通过氢键吸附正己烷溶液中苯酚的, 而其对水中苯酚的吸附是基于氢键和疏水作用的协同.

Macroporous crosslinked poly(p-vinylbenzylphenylether) resin, which can be abbreviated to phenylether resin, was synthesized from chloromethylated polystyrene. The adsorption isotherms of phenol onto phenylether resin from hexane and aqueous solution were measured, and the adsorption enthalpies were calculated. In addition, adsorption properties of phenol onto poly(p-vinylbenzylmethylether), phenylether resin, poly(p-vinylbenzyl-p-nitrophenylether), and poly(p-vinylbenzyl-p-methylphenylether) from hexane as well as those of phenol, 2,3,5-trimethylphenol, and p-nitrotoluene onto chloromethylated polystyrene and phenylether resin from aqueous solution were investigated. The results indicated that phenylether resin adsorbed phenol from hexane by hydrogen bonding, while it adsorbed phenol from aqueous solution through the cooperation of hydrogen bonding and hydrophobic interaction.
