Date Nov. 26, 1992A method of producing a solid thermoplastic-containing matrix by flash flow processing thermoplastic polymers as well as the products produced by such method is provided. The method involves subjecting a feedstock of a thermoplastic polymer to flash flow melt spin processing at a temperature of about 200-430 DEG F. and shear imposed by centrifugal force from an operating speed of about 3600-3800 rpm. The matrix thus prepared is in the form of a floss, fiber, flake, filament, ribbon, spicule and mixtures thereof A guest material such as a dye, a fragrance, a comestible, an oil, a photographic reducer and developer, an organism, an antioxidant and a medicament may further be incorporated into the feedstock prior to processing. |
