Polyurethane prepolymer and polyurethane elastomers, based on 1,4-naphthalene di-isocyanate

摘要

Polyurethane prepolymers and polyurethane elastomers based on 1,4-naphthalene are described. Methods of preparing the polyurethane prepolymers and elastomers are also described. Molded articles capable of withstanding high mechanical stresses, prepared from the polyurethane prepolymers and/or polyurethane elastomers of the present invention, are further described.
