SYNTHETIC THICKENER, AQUEOUS COMPOSITION AND PRINTING PASTE CONTAINING THE SAME, AND PROCESS FOR PREPARING THE SAME

摘要

The invention relates to synthetic thickeners for use in textile printing pastes. The thickeners are prepared by copolymerizing in a water-in-oil emulsion a) an olefinically unsaturated acid. such as acrylic acid, b) a salt of this acid, such as ammonium acrylate, c) a polyfunctional monomer such as methylenebisacrylamide, d) an olefinically unsaturated monomer containing a nitrile group, such as acrylonitrile and, optionally, e) an olefinically unsaturated monomer having hydrophilic functional groups, such as acrylamide. / P P Application Field: Textile Printing. / P
