Vibrationsabsorbierendes gummielastisches Verbundmaterial, Verfahren zu dessen Herstellung sowie dieses enthaltender Schwingungsdämpfer

摘要

Vibration-absorbing elastomeric composites, having improved vibration-damping properties with improved woldability and resin properties suitable for molded products, are obtained by reacting, insitu in a melted thermoplastic resin such as olefin-diene copolymer, a polyisocyanate with a polyol to for a polyurethane having a nitrogen atom content of at least 3 % and having a solubility parameter which is higher by at least 2.5 than that of said thermoplastic resin.
