Polymer beads have been prepared by photocationic suspension polymerisation of 2-(aryldimethyl)silyl ethers in perfluorooctane in the course of our studies on polymer-supported desymmetrisation of 1-silacyclohexa-2,5-dienes. Good yields of 100–200 μm beads of satisfactory shape have been obtained using a perfluorinated co-polymer as stabilising agent. These beads have no permanent porosity although they have a high nominal cross-linking level. Their swelling in common organic solvents is comparable with those of Merrifield or TentaGel gel-type resins.
在我们的研究过程中,通过2-(芳基二甲基)
硅醚的光阳离子悬浮聚合,在
全氟辛烷中制备了聚合物珠。使用
全氟化共聚物作为稳定剂,获得了形状满意、粒径为100-200微米的珠粒,产率良好。这些珠粒虽然没有永久孔隙,但具有较高的标称交联
水平。它们在常见有机溶vents中的膨胀程度与Merrifield或TentaGel凝胶型
树脂相当。
