Abstract: Defoamers in which the oil phase of the emulsions contains… (a) a C12- to C26-alcohol, distillation residues obtainable during the production of alcohols with a relatively high carbon number by oxo synthesis or by the Ziegler process and which may also be alkoxylated, and/or… (b) a fatty acid ester of C12- to C22- carboxylic acids with a mono- to tri-hydric C1- to C18-alcohol and optionally… (c) a hydrocarbon having a boiling point above 200 DEG C or fatty acids having 12 to 22 carbon atoms,… comprises 5 to 50% by weight of the make-up of the emulsion and has a mean particle size of less than 25 mu m, and in which 5 to 50 % by weight of the components (a) and (b) of the oil phase are replaced by… (d) at least one compound melting at a temperature above 70 DEG C selected from the group of fatty alcohols having at least 28 C atoms, the esters of a C1- to C22-carboxylic acid with an alcohol having at least 28 C atoms, the polyethylene waxes having a molecular weight of at least 2000, the carnauba waxes, the montanic ester waxes and the montanic acid waxes and their salts.

Abstract: Paper sizing agent mixtures of: (A) finely divided aqueous dispersions of C14 to C22 alkyl diketenes obtainable by dispersing the alkyl diketenes in water in the presence of cationic starch with an amylopectin content of at least 95 wt.%, and (B) finely divided aqueous polymer dispersions forming a paper sizing agent, process for producing the paper sizing agent mixtures by mixing th e components (A) and (B) and the use of the paper sizing agent mixtures as mass and surface sizing agents for paper, pasteboard and cardboard.

Abstract: According to a paper, paperboard and cardboard internal sizing process, resin size is used, as well as cationic polymers containing polymerized vinylamine units as fixing agents for the resin size.
