    • The object is to provide: a method for producing a polymer having a stable right-handed or left-handed helical structure from a single type of monomer in a per-selective manner and controlling the proportion between a polymer having the right-handed helical structure and a polymer having the left-handed helical structure; and a polymeric material which can be used for the formation of any of the right-handed and left-handed helical structures. Thus, disclosed are: a method for production of a polyisocyanide derivative having a stable helical main chain structure with a right-handed or left-handed helix or a mixture thereof from a single type of monomer by polymerizing an aromatic isocyanate having a substituent harboring a structure —CONH in the aromatic ring and a hydrophobic moiety having 6 or more carbon atoms in a polymerization solvent, wherein the direction of the helix depends on the polarity of the polymerization solvent; a poly(aromatic isocyanide) derivative produced by the method; and an aromatic isocyanide which is useful as a monomer for use in the production of the poly(aromatic isocyanide) derivative.
    • 本发明的目的是提供一种用于从单一类型的单体以每种选择的方式制备具有稳定的右旋或左旋螺旋结构的聚合物的方法,并且控制具有右旋螺旋结构的聚合物之间的比例 和具有左旋螺旋结构的聚合物; 以及可以用于形成任何右旋螺旋结构和左旋螺旋结构的聚合物材料。 因此,公开了以下方法:通过使含有具有取代基的取代基的芳族异氰酸酯聚合,从单一类型的单体制备具有具有右旋或左旋螺旋的稳定螺旋主链结构或其混合物的多异氰化物衍生物的方法 芳香环中的结构-CONH和在聚合溶剂中具有6个或更多个碳原子的疏水部分,其中螺旋的方向取决于聚合溶剂的极性; 通过该方法制备的聚(芳族异氰化物)衍生物; 以及可用作制备聚(芳族异氰化物)衍生物的单体的芳族异氰化物。
