Abstract: A process for increasing the chemical resistance of a polymeric composition is provided. The method includes a step of blending: a) the (meth)acrylic polymer AP1 and b) a copolymer CP1. The copolymer CP1 includes at least 41 wt % of vinyl aromatic monomer units by weight of the copolymer CPI. The polymeric composition includes at least 5 wt % of the copolymer CP1, by weight of the polymeric composition. A chemical resistance of the polymeric composition is better than a chemical resistance of the (meth)acrylic polymer AP1 without CP1. Chemical resistance is measured by a time to crack at 120° C. when subjected to an outer radius bending strain of 75% and wetted with a cloth soaked in isopropanol 99%.

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.
