通过利用辐射引发聚合相对于热引发聚合的优点，即仅使用单体和致孔溶剂就足够了，并且不需要引发剂，制备了二甘醇二甲基丙烯酸酯和2-羟乙基-丙烯酸酯的共聚物整体料。结果表明，随着共聚单体中HEA含量的增加（18vol%），单体的孔径和亲水性均有所增加。这些整料的比表面积约为1 m2/g。通过改变溶剂可以调节多孔性，几种洗脱液的流速测量表明这种整体柱可以用作色谱柱。这通过几种氨基酸的分离来说明。(c)2007爱思唯尔有限公司保留所有权利。
Copolymer monoliths of diethyleneglycol dimethacrylate and 2-hydroxyethyl -acryl ate were prepared by using the advantage of radiation initiated polymerization over the thermally initiated polymerization, namely, that it is sufficient to use only a monomer and a porogenic solvent and no initiator is needed. Besides, the reaction can take place at any desired temperature in a mold of suitable size and shape.The results showed that increase of the HEA content in the comonomer mixture (up to 18 vol%) resulted in monoliths with increased pore size and hydrophilic character. The specific surface area of these monoliths was in the order of 1 m(2)/g. The porous properties could be fine-tuned by changing the solvent.Flow rate measurements for several eluents indicated that these monoliths could be useful as chromatographic columns. This is illustrated by separation of several amino acids. (c) 2007 Elsevier Ltd. All rights reserved.
