Abstract (en)

[origin: WO2018197485A1] The present invention relates to a filament or fibre absorbing odorous molecules, in particular acid and/or basic gases, having a predetermined outer surface in which at least one portion of said surface comprises -COOH carboxylic groups and/or -COO- carboxylate groups complexed with metal salts. Said portion is advantageously made up of a matrix obtained from the reaction of a mixture comprising a polyester as well as a first copolymer of at least one olefin and alkyl (meth)acrylate and/or (meth)acrylic acid (A), and a second (co)polymer comprising -C2H3O(B) oxirane groups, at least one portion of the (meth)acrylate functions of the copolymer (A) having been transformed into corresponding carboxylate and/or carboxylic functions.
