  • Patent number: H2077
    Abstract: Dispersions in water of “poly{vinyl alcohol}” (“PVA”), preferably those types resulting from about 90 mole % hydrolysis and/or ester interchange of polymers of vinyl carboxylates and having a molecular weight of about 155,000, are particularly effective for modifying the surfaces of plastic materials to cause water and/or other specified liquids to spread more readily over the treated surfaces than over the untreated surfaces. A biocide to repress the growth of micro-organisms in the dispersions is preferred.
