FIELD: chemistry.
SUBSTANCE: present invention relates to production of cross-linkable aramide copolymer compositions and articles made therefrom. The composition contains an aramide copolymer obtained from monomers containing 1,4-phenylenediamine and tetraphthaloyl dichloride, and having at least one arylene-carboxylic acid link and at least one hydroxyarylene link. Alternatively, the composition contains an aramide copolymer obtained from monomers containing 1,4-phenylenediamine and tetraphthaloyl dichloride, and having at least one arylene-carboxylic acid link or at least one hydroxyarylene link and a covalent cross-linking agent. The invention also relates to cross-linked copolymers obtained from said composition and moulded articles containing such cross-linked copolymers.
EFFECT: invention enables to obtain materials with improved operational properties.
