超分子线性聚丙烯酰胺（SL-PAM）是通过β-环糊精（β-CD）二聚体和金刚烷封端聚丙烯酰胺（AT-PAM）的主客体相互作用制备的。以单6-脱氧甲苯磺酰基-β-环糊精和对苯二胺合成β-CD二聚体。 AT-PAM 采用金刚烷封端的三硫代碳酸酯（ATT）作为链转移剂，通过可逆加成断裂链转移自由基聚合（RAFT）制备。通过1H NMR确定了β-CD二聚体和AT-PAM的结构。对 SL-PAM 样品进行 2D NOESY NMR 和热分析以验证包合物的形成。还研究了 SL-PAM 的耐盐性和耐温性。与聚丙烯酰胺相比，SL-PAM的耐温性没有明显优势，但在一定盐度范围内，SL-PAM的耐盐性良好。
Supramolecular linear polyacrylamide (SL-PAM) was prepared by host–guest interaction of β-cyclodextrin (β-CD) dimmer and adamantane-terminated polyacrylamide (AT-PAM). The β-CD dimmer was synthesized by mono 6-deoxytosyl-β-cyclodextrin andp-phenylenediamine. AT-PAM was prepared by reversible addition-fragmentation chain transfer radical polymerization (RAFT) using the adamantane-terminated trithiocarbonate (ATT) as chain transfer agent. The structures of β-CD dimmer and AT-PAM were determined by1H NMR. 2D NOESY NMR and thermal analysis of SL-PAM sample were carried out to validate the formation of the inclusion complex. The salt tolerance and temperature resistance of SL-PAM were also investigated. Compared with polyacrylamide, the temperature resistance of SL-PAM has no obvious advantage, but salt tolerance of SL-PAM is good within a certain range of salinity.
