Abstract

The method comprises the following phases: mixing a certain amount of molten polymer, said polymer consisting essentially of oxidized polyethylene or a polyethylene- acrylic acid copolymer, with sufficient base to saponify and neutralize said oxidized polyethylene or to neutralize said polyethylene-acrylic acid copolymer establishing contact of said molten polymer in the presence of an anionic or non-ionic surfactant with a sufficient amount of an aqueous solution to form an emulsion dispersion of a quantity of fluorescent bleaching agent in said emulsion, said fluorescent bleaching agent being in a ratio of between approximately 1:1.5 and 1:3 by weight to the emulsified polymer and slowly adding sodium hypochlorite dissolved in an aqueous solution to the dispersed ultramarine blue and emulsified polymer until the emulsion breaks.
