<p>A process useful for drinking paper, comprising: (a) Mixing an aqueous solution containing linked paper, the aqueous solution optionally containing an ethylene oxide and butylenes oxide block polyol, to dissolve ink from the paper into aqueous solution; and (b) Subjecting the aqueous solution resulting from the above process to flotation, with the provision that the aqueous solution contains the ethylene oxide and butylenes oxide block polyol during flotation, whereby the polyol and ink form a flotation mass on the aqueous solution. The disclosed is used in effective amounts to reduce or inhibit the deposition of white pitch on the paper making equipment during the processing to recycle coated paper.</p> |
