Abstract
PURPOSE: To improve the soundproofing and vibration damping properties of a trestle and to prevent the attenuation of sound effects by hardening a liq. polymer compsn. consisting of prescribed substances. CONSTITUTION: A liq. polymer compsn. consisting of a liq. diene polymer having hydroxyl groups and a polyisocyanate compd. is poured into a mold of a prescribed shape, hardened and released from the mold to obtain the objective trestle 1 made of the resultant hardened body itself.
