Abstract
PURPOSE: A soundproof material composed of hydrogel that is obtained by crosslinking a water-containing and water-soluble polymer, thus developing good soundproof properties when sandwitched in between glass panes.
CONSTITUTION: A water-soluble polymer, preferably a polyvinyl alcohol derivative bearing unsaturated bonds and carboxyls as side chains or a water-soluble unsaturated monomer preferably a mixture of one monomer bearing 2 or more unsaturated bonds and the other monomer bearing one unsaturated bonds is dissolved in water to form an aqueous solution of 1W50wt% concentration. The solution is poured into a tranparent vessel and crosslinked with a radical polymerization catalyst such as hydrogen peroxide to produce the objective soundproof material composed of hydrogel.
