用金属卟啉络合物引发合成高分子量聚醚

The Synthesis of High Molecular Weight Polyether Initiated by Metalloporphyrin Complex

介绍了用四苯基卟啉铝络合物催化体系合成高分子量聚醚的方法。该聚合过程显示出一种持续特性。产物具有均一的链长和极窄的分子量分布，且数均分子量Mn可通过改变单体与引发剂的摩尔比来控制。

This paper introduces the synthesis of the high molecular weight polyether by using metalloporphyrin complex catalyst system. The process shows an immortal nature. The final product possesses uniform chain length and very narrow molecular weight distribu tion. And the Mn can be controlled by changing the mole ratio of monomer to initiator.
