| titleOfInvention | A kind of polyurethane polymer suitable for viscosity adjustment of aqueous high solvent system and composition containing the same |
| abstract | The present invention relates to a polyurethane polymer suitable for viscosity adjustment of an aqueous high solvent system and a composition containing the same. The polyurethane polymer comprises, on the polymer backbone, a hydrophobic structure having a functional group reactive with an isocyanate bond, and one or more monofunctional hydrophobic end-capped structures, the hydrophobic structure having a functional group reactive with an isocyanate bond Comprising 4 to 70 carbon atoms excluding the carbon atoms of the linker, the monofunctional hydrophobic end-capped structure comprises 8 to 30 carbon atoms excluding the carbon atoms of the linker. The present invention introduces a hydrophobic structure of functional groups that can react with isocyanate bonds on the main chain of the polyurethane polymer, and the hydrophobic structure can form a "cage-like" structure on the main chain of the polyurethane polymer, which can effectively interact with the solvent in the system. , reduce the influence of solvent on system thickening, especially in high solvent system, it has high thickening efficiency. |
