| 摘 要： | 以n-BuLi/(Cy2N)Cu为引发剂，在﹣15℃的四氢呋喃中，实现了极性单体甲基丙烯酸缩水甘油酯（GMA）的阴离子聚合，并研究了它与甲基丙烯酸甲酯(MMA)的共聚。结果表明，在c(n-Bu(Cy2N)CuLi)为0.158mol/L、cGMA为0.378 mol/L时，GMA的转化率达94.6%，M( ——)n 为5609，M￣w/￣n 为1.46。此外，该催化剂可使GMA和MMA发生共聚反应，共聚物中PGMA的含量为52%。

| Abstract: | Anionic polymerization of glycidyl methacrylate (GMA) has been carried out with n-BuLi/(Cy2N)Cu as initiator in THF below -15℃. Its copolymerization with methyl methacrylate (MMA) was also studied. It is demonstrated that the percentage of conversing monomer could reach to 94.6%, Mn is 5609 and Mw￣/M￣n is 1.46 when c(n-BuCy2NCuLi) is 0.158 mol/L and cGMA is 0.378 mol/L. Furthermore, the copolyers of GMA and MMA was resulted by the catalysts and the content of poly(glycidyl methacrylate) in the product is about 52%. |
