  • Process for the manufacture of paper and paperboard
    Patent number: 10113270
    Abstract: Process for the Manufacture of Paper and Paperboard The present invention relates to a process of making paper or paperboard in which a cellulosic thin stock is provided and subjected to one or more shear stages and then drained and a moving screen to form a sheet which is dried, wherein the process employs a retention system which is applied to the thin stock, said retention system comprising as components i) a blend of different cationic polymers and ii) a microparticulate material, in which the blend of cationic polymers comprises, a) a cationic polymer having a charge density of from 0.
    Type: Grant
    Filed: January 9, 2014
    Date of Patent: October 30, 2018
    Assignee: BASF SE
    Inventors: Christopher Alan Gray, Antonius Moormann-Schmitz, Hubert Meixner, Luis Miguel Sanchez Cerro, Thomas Muehlenbernd, Christian Jehn-Rendu
