SYNTHETIC PAINT THICKENER COMPATIBLE WITH DYE Russian patent published in 2010 - IPC C09D7/00 C08F283/06 C08F290/06 C08F290/14 C08L101/02 C08L101/04 C08L101/14 

FIELD: chemistry.

SUBSTANCE: invention relates to a synthetic thickener used in compositions for making paints. The synthetic thickener contains a water-soluble or water-swellable synthetic polymer whose main chain contains terminal and/or intermediate blocks of oligomeric hydrophobic fragments. The hydrophobic fragments are selected from a group which includes alkyl or aryl fragments which contain a polymerising cyclic monomer or mixture thereof. The monomer is selected from a group which includes alkyl glycidyl ethers, aryl glycidyl ethers, alkyl epoxy and mixtures thereof. Alternatively, hydrophobic fragments are selected from a group which includes polymerising alkene or mixture thereof and derivatives thereof. The polymerising alkene monomer is selected from a group which includes styrene and styrene compounds. The main chain of the water-soluble or water-swellable synthetic polymer is selected from a group which includes polyethylene glycol, polyacetal polyethers and polyurethane. The synthetic thickener can be used as a modifier of rheological characteristics, especially in latex paints.

EFFECT: use of the synthetic thickener in water-based coatings ensures good thickening, levelling and insignificant drips.
