Abstract (en)
[origin: WO9413883A1] The present invention relates to a process for the preparation of hydrophobic sizing agent dispersions used in the paper and board industry. The invention is both a simple and an economical way of preparing a hydrophobic sizing agent dispersion either in the premises of a sizing agent supplier or a paper maker. The invention is based on a usage of a so-called high-pressure digester in the preparation of a hydrophobic sizing agent dispersion.
