Notes: Abstract The leading term of the high-temperature quantum corrections to the scaled particle theory of the hard sphere fluid have been obtained. This provides approximate corrections to the pressure, surface tension, and reversible work to create a spherical cavityW(r) of the quantum mechanical hard sphere fluid. A number of exact identities valid for the classical hard sphere fluid are shown to apply also to the quantum mechanical hard sphere fluid, including the fluctuation relation betweenW(r) and the probability of finding a cavity of radius at leastr.

Notes: The fracture surface topography of simultaneous interpenetrating polymer networks (SIN'S) of poly (2,6-dimethyl-1,4 phenylene oxide) (PPO)/poly (butadiene) diol was examined by scanning electron microscopy (SEM). The phase morphology of the IPNs is highly dependent on PPO/poly (butadiene) diol mass ratio. A single-phase morphology of the IPNs was achieved when the content of poly (butadiene) diol is below 40 wt % in the initial composition. The SEM observations are also wholly consistent with the glass transition temperature behavior obtained in the differential scanning calorimetric (DSC) measurements. © 1994 John Wiley & Sons, Inc.
