Well-defined pentablock copolymers are prepared using a single catalyst, in one pot, from four different monomers: anhydride, epoxide, lactone, and CO₂. The dizinc catalyst bridges three distinct polymerization cycles and performs a double switch in polymerization mechanism to produce pentablock copolymers. The new materials are hydroxyl-telechelic and are efficiently postfunctionalized to introduce polar and nonpolar side-chains.

使用可切换的Dizinc催化剂从Tetracomponent单体混合物中获得Pentablock共聚物

定义明确的五嵌段共聚物是使用一种催化剂在一个罐中由四种不同的单体：酸酐，环氧化物，内酯和CO ₂制备的。二锌催化剂桥接了三个不同的聚合循环，并在聚合机理上进行了双重转换，以生产五嵌段共聚物。这种新材料是羟基telechelic，可以有效地后官能化以引入极性和非极性侧链。
