    Notes: Summary Binary blends of poly(vinylidene fluoride), PVDF, with cellulose acetatebutyrate (CAB) were characterized by using differential scanning calorimetry (DSC), wide angle X-ray scattering (WAXS) and Fourier transform infrared spectroscopy (FTIR). This system was proved to be partially miscible, showing a significant decrease on the thermal parameters (ΔHf and Tm) as well as on the crystallinity index (CI) of PVDF with CAB content on the second DSC run. γ crystalline form of PVDF, which is predominant in the as-cast blends, changed to α form with the first DSC run. In contrast, thermal treatment at 200°C (30 min) on blends containing 40–60 wt. % of CAB caused the γ phase to be predominant, as observed by FTIR.

    Notes: The physical properties, thermal stability, and interaction with liquids of cellulosic fibers isolated from henequen fibers (Agave fourcroydes) by an alkaline digestion process were determined. Physical dimensions, apparent length, and diameter of henequen cellulosic fibers were determined by optical microscopy in a random sample of 125 fibers. Other properties such as crystallinity, specific gravity, and cellulose type were also determined. The sorption of several liquids in these cellulosic fibers was measured and correlated to the polar and hydrogen bonding components of the solubility parameters of the liquids. The results show that, in general, henequen cellulosic fibers have properties that are in close agreement with those found in other cellulosic materials from natural sources. © 1995 John Wiley & Sons, Inc.
