Title:
ポリマー分散剤の製造のための乾燥助剤としての水溶性ポリマーの使用
Document Type and Number:
Japanese Patent JP4386831
Kind Code:
B2
Abstract:
The invention relates to the use of water-soluble polymers, consisting of a) monoethylenically unsaturated monomers consisting of acidic groups in an acidic, partially or fully neutralized form and b) other monomers which can be copolymerized with monomers a) as a drying agent for the production of redispersion power and/or powdery polymer dispersing agents. The water-soluble polymers contain at least 20 wt. % monomers (a) and a maximum of 8O wt. % monomers (b) and are supplied to the production process in the form of aqueous solutions in amounts of up to 50 wt. % maximum, enabling powder, polymer products with a residual moisture of <2 wt. % to be obtained, particularly in spray drying processes, and which are added to mineral systems as dispersing agents in amounts of 0.05-5 wt. % or are used as building materials for the mineral binding of redispersion powder in adhesives or as a binders in their own right.
