Abstract
Vibration-absorbing elastomeric composites, having improved vibration-damping properties with improved moldability 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 form 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.
