The latent dispersants were made by hydrogenation of an alkyl cetene dimer, alkenyl dimer, or cetene multimer. Adding the latent dispersant to paper or cardboard increased its resistance to water vapor and water while maintaining recycling and repulpability. In addition, a method was provided to increase the repulpability of a wax-coated paper or cardboard. Dispersants made by the hydrolysis of the alkyl cetene dimer, alkenyl dimer, and cetene multimer are also described. |
