Wide-angle X-ray scattering (WAXS) patterns of isotactic polypropylene (iPP) were analyzed in terms of the ideal WAXS patterns of their individual phases. Analysis was done with the technique of simulated annealing. This analysis is a novel method for simultaneously obtaining the volume fractions of the crystalline and amorphous phases and the average lamellar thickness of the individual crysta...
The objective of this study was to improve interfacial adhesion properties at the interface of thermomechanical pulp (TMP) fiber and isotactic polypropylene (iPP) using thermoset adhesives such as phenol formaldehyde (PF) and urea formaldehyde (UF). This study also attempted to achieve fiber-to-fiber adhesion using thermoset adhesives before the molten iPP would flow into the fiber web. The fra...
A series of 0-3 metal oxide-polyolefin nanocomposites are synthesized via in situ olefin polymerization, using the following single-site metallocene catalysts:C2-symmetric dichloro[rac-ethylenebisindenyl]zirconium(IV),Me2Si( BuN)(η-C5Me4)TiCl2, and (η -C5Me5)TiCl3 immobilized onmethylaluminoxane (MAO)-treated BaTiO3, ZrO2, 3-mol%-yttria-stabilized zirconia, 8-mol%-yttria-stabilized zirconia, sp...
