Poly(1-carbamoylethylene) is synthesized by introducing carboxylate substituents onto acrylamide backbone, producing a polymer chain that carries both amide and carboxyl functional groups. This dual functionality increases the polymer’s ability to form hydrogen bonds and ionic interactions with iron oxide surfaces, resulting in strong liquid bridging during the seeding and balling stages. The enhanced surface adhesion improves green pellet cohesion and density, promoting uniformity and reducing fines prior to induration.
