PROBLEM TO BE SOLVED: To provide a method for synthesizing a block copolymer based alloy including at least one rigid polyamide block PA.SOLUTION: The method includes the steps of: a) producing at least one polyamide block PA; and b) adding, during step a) to the block copolymer, 0.1 to 30 wt.% of at least one organic salt in a molten state relative to the total weight of the alloy. The obtained alloy has improved antistatic properties and identical mechanical properties compared to the same copolymer produced without adding an organic salt of the weight. The invention also relates to a block copolymer alloy having improved antistatic properties, to the use thereof in a polymer matrix, and to a composition containing the same. 【課題】少なくとも一つのリジッドなポリアミド・ブロックPAを有するブロック共重合体をベースにしたアロイの合成方法。【解決手段】（a）少なくとも一種のポリアミドブロックPAを作り、（b）段階（a）中に少なくとも一種の有機塩を溶融状態でアロイの総重量に対して0.1〜30重量％だけブロック共重合体に添加する。得られたアロイが改良された静電気防止特性を有し且つ重量の有機塩を加えない製造した同じコポリマーと比較して全く同じ機械特性を有する。本発明はさらに、帯電防止特性が改良したブロック共重合体アロイと、そのポリマーマトリックスでの使用と、それを含む組成物にも関する。【選択図】なし
