Abstract
Official abstract text for this publication.
The use of polyelectrolyte complexes is described, for providing an oxygen barrier to packaging materials made of polymer foils. Polymeric components of the polyelectrolyte complex are applied in polymerized form to the polymer foil. The polymer foil is either coated with an aqueous dispersion comprising a dispersed polyelectrolyte complex previously produced by water-in-water emulsion polymerization, or is coated with a composition comprising a polyelectrolyte complex produced from anionic polymer and from cationic surfactant, or the polymer foil is coated with at least three alternating layers, where respectively one of two adjacent layers comprises an anionic polyelectrolyte component and the other of two adjacent layers comprises a cationic polyelectrolyte component, and polyelectrolyte complexes form at the opposite, adjacent interfaces of the alternating layers.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of coating a polymer foil, the method comprising applying a mixture to at least one side of the polymer foil, wherein the mixture comprises (i) an aqueous dispersion comprising a dispersed polyelectrolyte complex comprising a cationic polymer produced by water-in-water emulsion polymerization, wherein the cationic polymer is a polymer comprising a vinylimidazolium unit, a polymer comprising a vinylamine unit, a polymers comprising a dialkyla…
