Abstract
Compositions including at least one polyamide obtained by polycondensation of meta-xylylenediamine and of a dicarboxylic acid, as well as at least one copolymer based on methyl methacrylate and on acrylic and/or methacrylic acid, the said copolymer being advantageously at least partially neutralized with an alkali metal. These compositions exhibit a high melt viscosity at low shear rate, which facilitates their processing.
