An object of the present invention is to provide a means for improving the dryness of a coating film formed as a vibration damper and suppressing cracks and expansion on the coating film surface. The said subject is solved by using the thickener for vibration damper which consists of a polymer which has an alkali-soluble monomer unit and an associative monomer unit. The alkali-soluble monomer unit preferably has a carboxyl group, a sulfonic acid group or a phosphoric acid group or such a salt. In addition, the associative monomer unit is-(R 1 -O) n- XR 2 in the side chain (wherein, R 1 is a methylene group, ethylene group, propylene group or butylene group, n is 10 ~ 300 and X is directly And a group represented by a bond, -C (= 0)-or -C (= 0) NH-, and R 2 is a hydrocarbon group having 6 to 30 carbon atoms. |
