The present invention provides a multibranched polymer represented by the following formula (I), and a method for producing the multibranched polymer:
wherein A represents an organic group having 3 or more branched chains, Xa represents a linking group containing any atom of Groups 14 to 16 in the Periodic Table, Y represents a functional group having a structure capable of having an active halogen atom, Q represents an arm moiety having a repeating unit derived from a polymerizable unsaturated bond, m1 represents any integer of 1 to the number of branched chains of A, m2 represents the number of branched chains of A, n1 represents an integer of 0 or 1 or more, and Ra represents an organic group which is not associated with the polymerization reaction.
本发明提供了由下式(I)表示的多支化聚合物,以及生产这种多支化聚合物的方法:
其中 A 代表具有 3 个或 3 个以上支链的有机基团,Xa 代表含有元素周期表中第 14 至 16 族原子的连接基团,Y 代表具有可具有活性卤原子结构的官能团,Q 代表具有由可聚合不饱和键衍生的重复单元的臂分子,m1 代表 1 至 A 的支链数的任意整数,m2 代表 A 的支链数,n1 代表 0 或 1 或以上的整数,Ra 代表与聚合反应无关的有机基团。
