Beschreibung
Zusammenfassung:	A viscoelastic resin usable for a damping material, adamping adhesive and a sandwich type damping steel plate constituted of steel plates and a viscoelastic resin layer sandwiched between the steel plates are disclosed. The viscoelastic resin is produced by reacting a diisocyanate, dicarboxylic acid or diamine with a base polymer selected from the group consisting of a polyester produced by reacting a dicarboxylic acid with a diol of the formula, HO - R - OH where R is an alkylene group which has at least one straight and/or branched alkyl side chain containing from 3 to 10 carbon atoms and of which the main chain connecting the two OH groups has from 3 to 12 carbon atoms and a polyurethane produced by reacting said diol with a diisocyanate.
