More Information
Summary:Synthesis of an alloy based on block copolymer comprising at least one rigid block polyamide (PA), comprises (a) preparation of the block copolymer, and (b) adding at least one organic salt (0.1-30 wt.%), which is melted, to at least one part of a block copolymer, during the step (a), to obtain alloy having improved antistatic properties and identical mechanical properties, compared to the same copolymer manufactured without addition of organic salt. Independent claims are included for: (1) a block copolymer alloy having improved antistatic properties, comprising at least one rigid polyamide block and at least one soft block, obtained by the process, where the alloy comprises at least one organic salt (0.1-30 wt.%); and (2) a composition comprising copolymer alloy, where the alloy is present at 5-100%, preferably 5-30% of the composition.
