摘要
利用膦腈碱(t-BuP4)为催化剂在室温下催化甲基丙烯酸烯丙酯(AMA)的进行基团转移聚合(GTP)反应,制备含悬垂双键的线型聚合物,并通过核磁(1 H NMR)、红外(FTIR)、凝胶渗透色谱(GPC)等对其进行分析和表征。结果表明t-BuP4催化AMA的GTP反应1h内,单体转化率就接近100%;聚合反应是通过AMA上的甲基丙烯酸酯双键进行,烯丙基双键不参与聚合反应;所得聚合物Mark-Houwink常数为0.75;使用极性溶剂更有利于加强聚合反应的可控性。
Vinyl functional polymers have received significant attention due to their high reactivity of double bonds.However their syntheses still present challenges to keep one reactive vinyl group in each repeat unit.Here,these polymers were successfully synthesized by the phosphazene bases（t-BuP4）catalyzed group transfer polymerization（GTP）of allyl methacrylate（AMA）.The synthesized polymers were characterized by Fourier transform infrared spectroscopy（FTIR）,nuclear magnetic resonance spectrometer（NMR）,and triple detection size exclusion chromatography（TD-SEC）.The results show that nearly 100%conversion of AMA was achieved within 1 hfor the t-BuP4 catalyzed system.The polymerization was processed by the reaction of the methacrylate double bonds in AMA.The Mark-Houwink parameter for the synthesized polymer is 0.75.The use of polar solvent helps to improve the level of control over the polymerization.
