摘要
以二乙胺、二硫化碳和丙酮为原料制备硫代氨基甲酸酯,再用硫代氨基甲酸酯和N-叔丁氧羰基-1,2-乙二胺反应,合成用于可逆加成-断裂链转移自由基(RAFT)聚合的链转移剂,接着进行N-乙烯基己内酰胺(NVCL)的RAFT聚合得到聚合物3,再氨解得具末端巯基的聚(N-乙烯基己内酰胺)。用核磁共振氢谱(1H NMR)与红外光谱(IR)证明目标产物已成功合成。
Thiocarbamate was synthesized by the reaction diethylamine with carbon disulfide and acetone. The thiocarbamate reacted with N-Boc-ethylenediamine to yield a chain transfer agent used to mediate reversible addition fragmentation chain transfer (RAFT) free radical polymerization. Then polymer 3 was prepared by RAFT polymerization of N-vinylcaprolactam (NVCL), which was mediated by the synthesized chain transfer agent. Finally, mercapto-terminated poly (N-vinylcaprolaetam) was synthesized by ammonolysis of polymer 3. The structures of the products were verified by 1H NMR and IR spectra.
