INFLUENCE OF FUNCTIONAL GROUP REACTIONS ON THE PORE STRUCTURE OF MACROPOROUS CROSSLINKED POLYSTYRENE RESINS*
摘要:
The change of the pore structure of styrene-divinylbenzene copolymer caused by the presenceof the functional group has been discribed in this paper. The result indicates that the average poreredius, pore volume and surface area were reduced after the introduction of the functional groups.However, the surfase area of the resin containing--NH2 or --NHCH3 group and treated with waterand isopropyl alcohol was inareased prominently in comparison with that of the matrix copolymer. When the strongly polar ion exchange resin absorbs water,its pore diameter increases sharply.But the pore diameter of the weakly polar ion exchange resin does not change very much when it absorbs water gradually.
