  • Polybutene molded article and method for making same
    Patent number: 4783301
    Abstract: The specification discloses a polybutene-1 polymer product and method and apparatus for making same in which the polymer is introduced into a form which defines the shape of the desired part and is then subjected to shear at a temperature from just above to just below the melting point of the polybutene-1 polymer, achieved by positioning the polymer blend between a shell and a mandrel and rotating the two relative to one another. When the viscosity of the polymer reaches a maximum, the part solidified and removed for subsequent use.
