ABSTRACT:
A process for selectively recovering vinyl halide insulation from mixed insulated wire scrap by selectively dissolving the vinyl halide insulation with a solvent at a temperature at which the solvent is a specific solvent for the vinyl halide and has no solvent effect upon other organic insulation material present in the mixed insulated wire scrap. The dissolved polyvinyl halide is recovered from solution in a dry granular state suitable for extrusion upon wire as insulation. The polyvinyl halide insulation is polyvinyl chloride, copolymers of polyvinyl chloride or mixtures thereof.
