    Notes: Abstract Seacliff State Beach, along the shoreline of northern Monterey Bay, California, has a well-documented history of repeated destruction and reconstruction of seawalls and park facilities. Seven times in 60 years the timber seawall has been destroyed by winter storm waves and subsequently rebuilt. The deficiencies of the wall, including (a) inadequate attachment of timber lagging to pilings, (b) inability of pilings or lagging to withstand repeated impact of waves and logs, and (c) inadequate height and internal drainage system have never been adequately addressed and each successive wall has essentially been identical to the previously destroyed wall.

    Thermal behavior, morphology, and some melt properties of blends of polycarbonate with poly(styrene-co-acrylonitrile) and poly(acrylonitrile-butadiene-styrene) (1988)

    Notes: Blends of bisphenol-A polycarbonate (PC) with poly- (styrene-co-acrylonitrile) (SAN) and poly (acrylonitrile-butadiene-styrene) (ABS) prepared by screw extrusion and solution-casting were investigated by differential scanning calorimetry and scanning electron microscopy. From the measured glass-transition temperatures (Tg) and specific heat increments (ΔCp) at the Tg, SAN appears to dissolve more in the PC-rich phase than does PC in the SAN-rich phase. Also, the decrease of Tg (PC) in PC/ABS blends is larger than in the PC/SAN blends. From the Tg behavior and the electron microscopy study, it is suggested that the compatibility increases more in the SAN-rich compositions than in the PC-rich compositions of the blends. In the study of extrudate swell of the PC/SAN blends and the PC/ABS blends, the maximum level of extrudate swell is reached at 0.5 weight fraction of PC for both blend systems. The Flory-Huggins polymer-polymer interaction parameter (χ12) between PC and SAN was calculated and found to be 0.034 ± 0.004. A similar value of χ for PC and SAN was found with the PC/ABS blends.
