摘要
本文描述了共辐照法丙烯腈在聚乙烯薄膜上的辐射接枝,该接枝体系的活化能由阿累尼乌斯公式求得为2.51 J·mol^(-1)。含偕胺肟和咪唑啉的两种功能高分子膜可以通过聚乙烯与丙烯腈的接枝共聚物分别与羟胺和乙二胺的化学反应制得。还对该两种膜在透过蒸发中的通量和分离系数作了比较。
The radiation grafting of acrylonitrile onto polyethylene film bymutual irradiation method was described in this paper. The energy of activation forthis system is 2.51 J. mol^(-1) calculated by Arrhenius equation. The functional poly-mer membranes containing amidoxime and imidozoline groups can be obtained by che-mical reaction of AN/PE graft copolymer with hydroxyamine and ethylenedieminerespectively. The flux and separction coefficient for both membranes in the process ofpervaporation were compared.
