FIELD: chemistry.
SUBSTANCE: invention relates to polyamide-based graft copolymers. Disclosed are graft copolymers based on polyamide which has reacted with a maleic anhydride, containing at least one vinyl-unsaturated side chain, selected from N-vinyl caprolactam and/or N-vinyl pyrrolidone and the polyamide component is at least one compound selected from natural or synthetic polyamides.
EFFECT: disclosed copolymers can be obtained from readily available starting materials using a relatively cheap and simple technique and are suitable for use as gas hydrate inhibitors.
