Acrylic and / or vinyl polymers and / or copolymers containing acid groups in which 60% to 90% of the active acid sites are neutralized by the magnesium ion, with a specific viscosity at most equal to 25 and of increased biodegradability, i.e. the degradation of which at after 36 days is greater than 50% according to the modified Sturm method. Application of these polymers to fields as diverse as paper, paints, plastics, petroleum, drilling fluids, water treatment, detergents, cosmetics, textiles, inks, leather, grinding and / or disintegration of minerals in water. |
