    • The aim of the present invention is to provide a multi-branched polymer, in which branch terminals can be easily modified and which have a high degree of branching and narrow dispersion. By polymerizing a compound having 2 or more polymerization-initiation sites and polymerizable unsaturated bonds with a living radical polymerization method using a metal catalyst, it is possible to produce a multi-branched polymer with narrow dispersion and a high degree of branching and having repeating units represented by the formula (I): wherein R1 to R3 each independently represents hydrogen or a hydrocarbon group, R1 may be bonded to R3 to form a ring; X represents a connecting group having a valence of 3 or higher; Y may be the same or different and each represents a functional group which may have a halogen atom at a terminal thereof; and a is an integer of 2 or larger.
    • 本发明的目的是提供一种多支化聚合物,其中分支端子可以容易地改性并且具有高度的支化度和窄的分散性。 通过使用金属催化剂通过活性自由基聚合法聚合具有2个以上聚合引发部位和聚合性不饱和键的化合物,可以制造具有窄分散性和高支化度的重复单元的多支链聚合物 由式(I)表示:其中R 1至R 3各自独立地表示氢或烃基,R 1可以与R 3结合形成环; X表示3价以上的连接基, Y可以相同或不同,表示可以在其末端具有卤素原子的官能团; a为2以上的整数。
