    Notes: [Auszug] SIR - Your recent view on reducing biology to physics1 ignores a fundamental problem. If biology is in principle reducible to physics, then so is psychology. Physics is quantumso that the prediction of behaviour would be in the form of a probability distribution of states: which state is observed ...

    The effects of morphological transitions on hydrogen bonding in polyurethanes: Preliminary results of simultaneous DSC-FTIR experiments (1986)

    Notes: The influence of morphological transitions on the hydrogen-bonding behavior of polyurethanes is investigated by simultaneous measurements of Fourier-transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC). The materials examined are a noncrystalline polyurethane hard segment, a crystallizable polyurethane hard segment, and a segmented polyurethane block copolymer containing crystallizable hard segments. Integrated absorbance data show that the hydrogen-bonding behavior is insensitive to crystalline transitions within the hard segment microdomains, but that it does reflect morphological transitions in the block copolymer that are associated with intersegmental mixing. In addition, the spectral data show conclusive evidence for reversal of the urethane reaction at high temperatures.
