patent specification: "composition and use of hydrogenated alkyl ketene dimers". The present invention relates to latent dispersants which have been manufactured by hydrogenating an alkyl ketene dimer, alkenyl ketene dimer, or ketene multimer. Addition of latent dispersant to paper or cardboard increased its water and water vapor resistance while maintaining recyclability and new pulping capacity. Additionally, a process is provided for increasing the pulping capacity of a wax coated paper or cardboard. Dispersants manufactured by hydrolysis of alkyl ketene dimer, alkenyl ketene dimer, and ketene multimer are also described. |
