Abstract
The object of the invention is to provide a means to enhance the drying property of a coating film formed as a vibration damper and repressing the occurrence of crack and expansion in the surface of the coating film. The task mentioned above is accomplished by using a thickener for vibration damper, which contains a polymer comprising an alkali-soluble monomer unit and an associating monomer unit. The alkali-soluble monomer unit may possess a carboxyl group, a sulfonic acid group, or a phosphoric acid group, or a salt thereof. The associating monomer unit may possess in a side chain thereof a group represented by the formula, —(R—O)—X—R, (wherein Rdenotes methylene group, ethylene group, propylene group or butylene group, n denotes a number in the range of 10-300, X denotes a direct bond, —C(═O)—, or —C(═O)NH—, and Rdenotes a hydrocarbon group of 6-30 carbon atoms).
