Abstract: MDI-based prepolymers are blown with a substantially nonaqueous blowing agent, such as pressurized air, and polymerized with stoichiometric amounts of polyoxyethylene polyol having at least two hydroxyl equivalents per mole, yielding a hydrophilic foam. The present foams may be extruded, knife-coated or otherwise cast into sheets, or may be fabricated by other known foam preparation techniques. Because the foam is polymerized with polyoxyethylene polyol instead of water, the foam exhibits both superior drape and improved stretch and recovery as compared with prior-art MDI-based flexible foams formed with aqueous reactants. The foam is particularly suited for use in external biomedical applications as, for example, a laminated medical/surgical dressing in which a thin sheet of the hydrophilic foam adheres to a nonstick aluminized veil on one side.

Abstract: A nuclear magnetic resonance spectrometry is disclosed in which a 90.degree. pulse and a 180.degree. pulse are applied to nuclei under observation at a time interval of t. Then, the resulting echo signal is observed after a period of t. Either a strong 90.degree. pulse of strong RF waves are applied to nuclei that are not observed. The strong RF waves decouple the nuclei not observed over a broad range. The application of the strong 90.degree. pulse or RF waves is initiated in synchronism with the 180.degree. pulse. The application of the RF waves are terminated before the beginning of the observation of the echo signal. The observation made in this way makes it possible to obtain spectra of quaternary carbons, the spectra including the information about long-range coupling.
