Abstract
Official abstract text for this publication.
The invention relates to a method for producing aqueous polyurethane-polyurea dispersions, aqueous polyurethane-polyurea dispersions produced by this method and their use to produce coating agents and adhesives.
First claim
Opening claim text (preview).
The invention claimed is: 1. Method for producing aqueous polyurethane-polyurea dispersions, wherein in a first step (I) an isocyanate-functional prepolymer free from urea groups is produced by complete or partial reaction of compounds A) polyisocyanates, B) polyols having number-average molecular weights of 400 to 8000 g/mol, C′) low-molecular-weight compounds having a molecular weight of 60 to 400, which in total have two or more hydroxyl groups, D′) optionally compounds h…
