Abstract
The invention relates to a method for synthesising a block copolymer alloy including at least one rigid polyamide block PA, including the steps of: a) producing said block copolymer; b) adding, during step a) and to at least a portion of said block copolymer, 0.1 to 30 wt % of at least one organic salt in the molten state relative to the total weight of the alloy, so that the alloy thus obtained has improved antistatic properties and identical mechanical properties when compared to the same polymer produced without adding an organic salt. The invention also relates to a block copolymer alloy having improved antistatic properties and obtained by said method, to the use thereof in a polymer matrix, and to a composition containing same.
