  • Extrusion processes using high melt strength polypropylene
    Patent number: 8546504
    Abstract: The present invention relates to a process comprising extruding a blend of an first propylene polymer comprising a non-phenolic stabilizer and a non-irradiated second propylene polymer, wherein the irradiation of the first propylene polymer was conducted in a reduced oxygen environment, and the irradiated first propylene polymer and the non-irradiated second propylene polymer were blended at a temperature below the melting point of the first and second propylene polymers.
    Type: Grant

  • Removal of oligomers from substantially crystalline, .alpha.-olefin polymers
    Patent number: 5703203
    Abstract: Disclosed is a method for removing oligomers from substantially crystalline, .alpha.-olefin polymer particles without having to melt the particles. The method comprises fluidizing a bed of the particles with a gas in which the oligomers are soluble, which bed is at a temperature at which the particles are not sticky, but at least lower molecular weight oligomers will evaporate therefrom, and maintaining the particles in the fluidized bed until a substantial portion of the oligomers have evaporated and have been removed from the bed by the fluidizing gas. By regulatng the bed temperature and the residence time of the particles in the bed the proportion and chain length of the oligomers removed can be controlled.
