SOLID READILY SOLUBLE NONIONIC SYNTHETIC ASSOCIATIVE THICKENERS WITH ADDITIVE WHICH PROMOTES DISSOLUTION AND IS SOLUBLE IN WATER Russian patent published in 2017 - IPC C09D7/12 C08L59/00 

FIELD: chemistry.

SUBSTANCE: present invention relates to a milled product containing a nonionic synthetic associative thickener (NSAT), a modifier of rheological properties, and water-soluble additive which promotes dissolution, and to introducing the milled product to water-based paints. Here is the description of milled product intended for the preparation of paints containing a nonionic synthetic associative thickener (NSAT), modifying the rheological properties and allowing the dissolution of a water-soluble additive, wherein NSAT rheology modifiers are selected from the group consisting of hydrophobically modified ethoxylated urethane (HEUR), hydrophobically modified polyethylene glycol (HMPEG) and hydrophobically modified polyacetal-polyether (NMRARE); the water soluble additive is sugar; and less than about 5 wt % of milled product is kept in the sieve (with 1.18 mm holes (No.16) as per the measurements according to the standard ASTM S136 - 06 Standard Test Method for Sieve Analysis of Fine and Coarse Aggregates. The method for producing the above-milled product is also described and it has the steps of: a) obtaining NSAT rheology modifier and dissolution-initiating water soluble additive; b) mixing of rheology modifier NSAT and dissolution-initiating water soluble additive; and c) preparation of milled product from step b) product. The variants of the method for introduction of the above milled product into aqueous system comprising a water-insoluble polymer.

EFFECT: invention provides improved milled product solubility in the paint containing a nonionic synthetic associative thickener (NSAT) rheology modifier.
