Block copolymers with chains of different structures in a molecule are expected as new polymer materials, and the syntheses require the selection of appropriate initiators for the living polymerization of corresponding monomers. We have already found that metalloporphyrins are excellent initiators for the living polymerization of a wide variety of monomers. The purpose of the present research is to establish the method of synthesis of block copolymers containing methyl methacrylate as a component, in view of industrial importance of poly (methyl methacrylate). As the result, we succeeded in the syntheses of block copolymers from methyl methacrylate and other alkyl methacrylates, alkyl acrylates, and methacrylonitrile, using aluminium polphyrin as initiator. Among these block copolymers, the property of methyl methacrylate methacrylonitrile copolymer is of particular interest, in that it forms micelles in appropriate solvents. The cast film exhibits a microphase separated structure, indicating the possibility of this block copolymer for application to novel polymer materials.

分子中具有不同结构链的嵌段共聚物有望成为新型高分子材料，其合成需要选择合适的引发剂来实现相应单体的活性聚合。我们已经发现金属卟啉是多种单体活性聚合的优异引发剂。鉴于聚甲基丙烯酸甲酯的工业重要性，本研究的目的是建立含有甲基丙烯酸甲酯作为组分的嵌段共聚物的合成方法。结果，我们以铝卟啉为引发剂，成功地合成了甲基丙烯酸甲酯与其他甲基丙烯酸烷基酯、丙烯酸烷基酯和甲基丙烯腈的嵌段共聚物。在这些嵌段共聚物中，甲基丙烯酸甲酯-甲基丙烯腈共聚物的性质特别令人感兴趣，因为它在适当的溶剂中形成胶束。流延膜表现出微相分离结构，表明该嵌段共聚物应用于新型聚合物材料的可能性。
