嵌段共聚物的合成技术有较大的可靠性和预见性,并可提供别的聚合物所不能达到的特殊性能。用基团转移聚合的方法进行丙烯酸酯类极性单体室温下的活性聚合,能得到具有预定链长、嵌段纯度和多分散性指数小的嵌段共聚物。用双官能团引发剂进行基团转移嵌段共聚,可减少加单体的次数,避免引进杂质,且能合成用单官能团引发剂所无法得到的A—B— Block copolymer synthesis technology has greater reliability and predictability, and can provide other polymers can not meet the special performance. The living polymerization of acrylate-based polar monomers at room temperature by group transfer polymerization gives a block copolymer having a predetermined chain length, a small block purity, and a low polydispersity index. Bifunctional group initiator group transfer block copolymer can reduce the number of monomer plus, to avoid the introduction of impurities, and can be synthesized with monofunctional initiator can not be obtained A-B-
