    摘要: The present invention relates to (co)polyamides comprising at least 85 mole % (mol.%) of recurring units (RPA) of formula (I): (I); the present invention also relates to polymer compositions comprising such (co)polyamides, as well as articles comprising the same and methods of using said articles in high temperature applications requiring sufficient swelling or deformation upon exposure to moisture, such as for example oil and gas extraction processes (e.g. fracturing balls), or as support materials used to print three-dimensional (3D) parts.
