When using CB, it has excellent affinity with polyamine (a) and/or modified polyamine (b) (hereinafter collectively referred to as polymer particles), so the treatment effect is large, and it is therefore effective for treating various substances.

る。Obtaining CB whose surface has been treated with a polyamine component is not necessarily achieved only by the production method of the present invention, but can also be achieved by other means such as, for example, a method of polymerizing ethyleneimine monomer in the presence of CB; However, the dispersibility in various materials and the effect as a modifier for various polymeric substances are not fully satisfactory. That is, in the method of polymerizing ethyleneimine monomer in the presence of CB, it is difficult to disintegrate CB in a secondary agglomerated state.
The resulting product contains CB in the form of coarse particles. On the other hand, the products manufactured by the manufacturing method of the present invention have small and uniform particle sizes. Also, the dispersibility in various materials is C
The molecular weight of the polyamine component used in the treatment of B has an important meaning, and it is usually preferable to control it to a high molecular weight, but it is extremely difficult to control the polyamine component to a desired molecular weight using methods other than the present invention. be.
