Disclosed is a method for producing a block copolymer which comprises two or more blocks composed of aromatic units having different basic structures from each other and has a high molecular weight, a narrow chain length distribution and a narrow molecular weight distribution. Also disclosed is a block copolymer produced by the method. The method for producing a block copolymer comprises the step of sequentially reacting two or more aromatic compounds which are selected from aromatic compounds represented by a specific general formula and are different in the group Ar, in the presence of a nickel complex containing a phosphine compound represented by a specific general formula or a palladium complex containing a phosphine compound represented by a specific general formula to thereby form blocks comprising the aromatic compounds sequentially, wherein the two or more aromatic compounds are reacted in descending order of parameter of aromatic ring charge.
本发明公开了一种生产块状嵌段共聚物的方法,该共聚物由两个或更多组成的芳香族单元块组成,这些单元块具有不同的基本结构,具有高分子量、窄的链长分布和窄的分子量分布。本发明还公开了通过该方法生产的块状嵌段共聚物。生产块状嵌段共聚物的方法包括以下步骤:在特定的一般式所表示的芳香族化合物中选择两个或更多个芳香族化合物,这些化合物在基团Ar中不同,并在含有特定一般式所表示的膦化合物的
镍络合物或含有特定一般式所表示的膦化合物的
钯络合物的存在下,依次反应这些芳香族化合物,从而形成含有这些芳香族化合物的块,其中这两个或更多个芳香族化合物按芳香环电荷参数的降序反应。
