  • Castable polyurethane elastomers chain extended with 2,3-bis(hydroxymethyl)bicyclo[2,2,1]heptane
    Patent number: 5047494
    Abstract: A castable polyurethane elastomer comprising the polymerization reaction product of a polyurethane prepolymer and 2,3-bis(hydroxymethyl) bicyclo [2,2,1] heptane as a chain extender. The elastomer has an advantageously low rebound property, which makes it particularly useful in shock absorber and anti-vibration mounting applications.
