摘要: 聚乙烯胺 ( 简称 PVAm) 是含有胺基的多功能聚合物，其功能胺基使得聚乙烯胺能进行一系列的氨基特征反应。在本论文研究中，以金属化合物 Pd(OAc)2 作为催化剂催化聚氯乙烯 (PVC) 在氨气条件下一步法胺化生成聚乙烯胺；生成的产物聚乙烯胺通过红外和核磁共振法来进行结构检测，并用电导滴定法来测定聚乙烯胺的胺化度。试验结果表明，在 40 ℃温度时，聚氯乙烯与氨气可在 Pd(OAc)2 催化下反应 4.5h 即可得到 46.5% 的产率和 78.5% 的胺化度。
Abstract: Polyvinylamine (PVAm) is a kind of attractive multi-purpose polymer with amino groups which provide a series of exceptional potential reactivities. In this work, metallic compound Pd(OAc)2catalyzed the synthesis of polyvinylamine by one-step method, with PVC as raw material and NH3as aminating agent. Structure of the target product PVAm·HCl was characterized by FT-IR and NMR and amination degree of polyvinylamine was determined by electro- conductivity titration. The yield and amination degree of the product over Pd(OAc)2reached 46.5% and 78.5%, respectively, at 40˚C, 4.5 h.
