Two seies of crosslinking Bakelits containing hydroxyl-group and polyglycol structure are synthesized by polycondensation of oligomeric hydroquienone polyglyeol ethers with formaldehyde in the presence of H 2 SO 4 .These polymers would contain different ring structures of pseudoerown ethers in their backbone,which may simulate the properties of the polymeric crown ethers.All of the new monomers and polymers are characterized by IR,UV, 1 H NMR. These polymeric compounds have good thermostability and can be used below 180℃.The study on eomplexing capacity indicated that enrichment efficiency of PFC-Ⅱ for Ag + ,Pb 2+ and some other metallic ions (10 -6 ～10 -4 mol·L -1 ) reaches 100%. 聚多缩乙二醇 氧化乙烯 假冠醚 oligomer ethylene glycol ether pseudocrown ether O644.14 1993-04-01 2021-04-01 4
