Abstract:
A method of producing a solid thermoplastic-containing matrix wherein said method comprises subjecting a solid feedstock comprising a thermoplastic polymer to flash flow melt spinning wherein said melt spinning is conducted at a temperature of about 200-430.degree. F. and shear imposed by centrifugal force from an operating speed of about 3600 to about 3800 revolutions per minute, thereby causing transition of said thermoplastic polymer from a solid having no internal flow to a second solid being in matrix form selected from the group consisting of a floss, fiber, flake, filament, ribbon, spicule, and mixtures thereof.
