Definitions

  • paper coating slips are used for the production of coated printing papers, which consist essentially of a pigment dispersed in water, for. B. kaolin, calcium carbonate or titanium dioxide, and one or more binders. While previously only high molecular natural products such as starch or casein were used as binders, attempts are increasingly being made to replace all or part of the natural products with synthetic, high molecular weight polymers in the form of an aqueous dispersion. Binders based on natural products have the disadvantages that they are not always of the same quality, are sensitive to the attack by microorganisms, have to be broken down by complex processes and produce brittle lines. Binders based on synthetic high polymers do not have all of the disadvantages of natural binders mentioned, but they still need to be improved.

However, it is also possible to copolymerize acrylic acid esters and methacrylic acid esters together with other ethylenically unsaturated compounds and to use them as a component of the binder combination. Ethylene or propylene, for example, are also suitable as comonomers.
  • Copolymers of butadiene and styrene are also suitable as copolymers of the binder mixture. These copolymers contain 20 to 60% by weight of butadiene and 40 to 80% by weight of styrene and / or acrylonitrile.
